A cut diamond sparkles due to its unique molecular structure. The facets of a diamond are designed to reflect and refract light internally, maximizing its brilliance and dispersion of colors, creating the sparkling effect known as “fire” in diamonds.

A coin placed in a vessel filled with water appears slightly raised due to the refraction of light. When light passes from water into air (or vice versa), it changes direction, making the coin appear higher than its actual position ...
To a person sitting and hanging in water, their leg appears bent and smaller due to refraction. This occurs because light bends as it travels from water into air, making objects viewed through the water’s surface appear distorted, closer, and ...
Polarization is the phenomenon that does not occur in both light and sound. While light waves can be polarized because they are transverse waves with oscillations perpendicular to the direction of propagation, sound waves are longitudinal waves with oscillations in ...
The bending of light from the core (edge) of a barrier is called diffraction. This phenomenon 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 theory that confirms the wave nature of light is the theory of interference. This theory demonstrates that light exhibits wave-like behavior through phenomena such as constructive and destructive interference patterns, which can only be explained if light behaves as ...
The nature of light radiation is similar to both wave and particle. This dual nature, known as wave-particle duality, is a fundamental concept in quantum mechanics, showing that light exhibits wave-like properties such as interference and diffraction, and particle-like properties ...
The phenomenon of light returning after hitting a smooth surface is called reflection. This occurs when light rays bounce off a surface at an angle equal to the angle at which they hit the surface, obeying the law of reflection.
The phenomenon of polarization in light proves that light waves occur transverse. Polarization occurs because the oscillations of light waves are perpendicular to the direction of propagation, allowing them to be aligned in a particular orientation.
The first person to discover the speed of light was Ole Rømer. In 1676, he observed the eclipses of Jupiter’s moons and noticed a discrepancy in their timing, leading him to calculate the finite speed of light.
