When a light ray moves from a denser to a rarer medium at an angle of incidence greater than the critical angle, it undergoes total internal reflection. This phenomenon occurs because the light ray cannot refract out of the denser ...

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.
The velocity of light is maximum in vacuum. In vacuum, light travels at its maximum speed, which is approximately 299,792,458 meters per second (or about 186,282 miles per second).
The photoelectric effect was proposed by Einstein. Albert Einstein, in 1905, explained the phenomenon where photons of light eject electrons from a material’s surface. This theory helped establish the concept of quantized energy of light and the particle-like nature of ...
