The phenomenon of polarization in light proves that light waves occur transverse, which corresponds to option [C]. Polarization is a property that only transverse waves exhibit, as it involves the orientation of the oscillations perpendicular to the direction of wave propagation. When light is polarized, its electric field vectors are aligned in a specific direction, filtering out waves vibrating in other directions. This can be achieved through various methods such as passing light through a polarizing filter, reflecting it off a surface at a specific angle (Brewster’s angle), or scattering it. The ability to polarize light confirms that its oscillations occur in planes perpendicular to the direction of travel, which is a characteristic of transverse waves. Longitudinal waves, such as sound waves, cannot be polarized because their oscillations occur in the same direction as the wave’s propagation. Thus, polarization is a definitive proof of the transverse nature of light waves, highlighting the distinct manner in which they propagate and interact with various media.

The phenomenon of light returning after hitting a smooth surface is called reflection of light, which corresponds to option [B]. Reflection occurs when light rays strike a smooth, shiny surface and bounce back into the medium from which they originated. This process follows the law of reflection, which states that the angle of incidence (the angle at which the incoming light ray hits the surface) is equal to the angle of reflection (the angle at which the light ray leaves the surface). Common examples of reflection include the way we see our image in a mirror or the way light glints off a calm body of water. Reflection is a fundamental concept in optics and is crucial for various applications, such as designing optical instruments, creating reflective surfaces in architecture, and even in everyday activities like using a periscope or applying makeup. The precise and predictable nature of light reflection allows it to be harnessed effectively in both scientific and practical contexts.

The nature of light radiation is similar to wave and particle both, which corresponds to option [C]. This duality is a cornerstone of quantum mechanics, describing how light behaves both as a wave and as a particle. As a wave, light demonstrates phenomena such as interference and diffraction, which are best explained by its wave nature. For example, Thomas Young’s double-slit experiment showed that light creates an interference pattern, a characteristic behavior of waves. As a particle, light is composed of photons, discrete packets of energy. The photoelectric effect, explained by Albert Einstein, demonstrated that light could eject electrons from a material, a behavior that can only be explained if light acts as particles. This wave-particle duality reconciles the seemingly contradictory behaviors and provides a comprehensive understanding of light’s complex nature, illustrating how it can simultaneously exhibit properties of both waves and particles.

The theory that confirms the wave nature of light is the theory of interference, option [B]. This theory illustrates how light waves can superimpose to produce patterns of constructive and destructive interference. When two or more light waves overlap, their amplitudes combine, resulting in an interference pattern. If the waves are in phase, they create constructive interference, leading to brighter regions. If they are out of phase, destructive interference occurs, resulting in darker regions. This behavior is a hallmark of wave phenomena and cannot be explained by particle theories alone. Experiments such as the double-slit experiment famously conducted by Thomas Young in 1801 provide clear evidence of this wave-like behavior of light. By observing the resulting interference patterns, scientists have conclusively demonstrated that light behaves as a wave, supporting the theory of interference as a fundamental explanation for the wave nature of light.
The bending of light from the core (edge) of a barrier is called diffraction, which corresponds to option [B].

The bending of light from the core (edge) of a barrier is called diffraction, which corresponds to option [B]. Diffraction occurs when a wave encounters an obstacle or a slit that is comparable in size to its wavelength, causing the wave to bend around the edges and spread out. This phenomenon is a fundamental aspect of wave behavior and can be observed with various types of waves, including light and sound. In the context of light, diffraction can create patterns of constructive and destructive interference, leading to effects such as the rainbow-like colors seen in a CD or the spreading of light when it passes through a small aperture. Unlike dispersion, refraction, and interference, diffraction specifically describes the bending and spreading of waves around obstacles.
Polarization, option [B], does not occur in both light and sound. Light waves can be polarized because they are transverse waves, meaning their oscillations are perpendicular to the direction of wave propagation.

Polarization, option [B], does not occur in both light and sound. Light waves can be polarized because they are transverse waves, meaning their oscillations are perpendicular to the direction of wave propagation. This property allows light waves to oscillate in various planes and thus be filtered or aligned in a specific orientation, which is what polarization refers to. On the other hand, sound waves are longitudinal waves, with oscillations occurring in the same direction as the wave propagation. This intrinsic nature of sound waves does not permit polarization because there is no perpendicular oscillation plane to align or filter. While both light and sound waves can experience diffraction, reflection, and refraction, which involve the bending of waves around obstacles, bouncing off surfaces, and changing direction when entering a different medium respectively, the unique transverse nature of light waves and longitudinal nature of sound waves means that polarization is not a shared phenomenon between them.

A lunar eclipse occurs on a full moon day, which corresponds to option [B]. During this celestial event, the Earth passes directly between the Sun and the Moon, with the three bodies aligning in a straight line. The Earth’s shadow then falls on the Moon, causing it to darken temporarily. The type of lunar eclipse—whether partial, total, or penumbral—depends on how deeply the Moon enters the Earth’s shadow. A total lunar eclipse occurs when the Moon passes completely through the Earth’s umbra (the central, darkest part of the shadow), while a partial lunar eclipse occurs when only a part of the Moon enters the umbra. A penumbral lunar eclipse occurs when the Moon passes through the Earth’s penumbral shadow, resulting in a subtle darkening of the lunar surface. Observing lunar eclipses provides valuable insights into Earth’s position in relation to the Sun and Moon and offers a breathtaking display of celestial mechanics visible from Earth.

To a person sitting and hanging in water, their leg appears bent and smaller due to refraction, which corresponds to option [A]. Refraction happens because light travels at different speeds in water compared to air. When light rays pass from water into air at an angle, such as when viewing a submerged object from above the water’s surface, they change direction due to the change in the medium’s optical density. This bending effect alters the apparent position and size of objects seen through the water, creating optical illusions. Objects partially submerged appear bent at the water’s surface, a phenomenon often observed in swimming pools or underwater photography. Understanding refraction is crucial in fields like optics, underwater exploration, and ophthalmology, where accurate knowledge of light’s behavior in different environments is essential for interpreting visual information and designing optical instruments.

A coin placed in a vessel filled with water appears slightly raised due to the refraction of light, which corresponds to option [B]. Refraction occurs because light travels at different speeds in different mediums, such as water and air. When light passes from water into air (or vice versa), its path bends at the interface due to the change in speed, following Snell’s law. This bending effect causes the coin to appear higher than its actual position when viewed from above the water’s surface. The amount of apparent displacement depends on the refractive indices of water and air and the angle at which the observer views the coin. This phenomenon is a common optical illusion that demonstrates how light behaves when it transitions between materials with different optical densities. Understanding refraction is essential in fields such as optics, astronomy, and underwater exploration, where accurate predictions of light’s behavior in various mediums are critical for scientific observations and practical applications.

A cut diamond sparkles due to total internal reflection, which corresponds to option [C]. The geometric arrangement of a diamond’s facets, combined with its high refractive index, allows light entering the diamond to bounce internally from facet to facet rather than escaping. This phenomenon, known as total internal reflection, ensures that a significant portion of light remains trapped within the diamond, enhancing its brilliance and dispersion of colors. The precise cutting of diamonds into facets optimizes this effect, scattering light into a spectrum of colors called “fire.” This inherent property of diamonds, stemming from their crystalline structure and high refractive index, distinguishes them as prized gemstones renowned for their exceptional sparkle and optical allure. Understanding the physics of light interaction within diamonds is crucial for gemologists and jewelers in evaluating and appreciating their beauty and value.
