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 ...
