Light Physics Quiz

Refraction is the bending of light as it passes from one medium to another, caused by a change in its speed. This change in speed is due to the change in the optical density of the medium.

In the wave theory, light exhibits properties such as diffraction and interference, while in the particle theory, light is composed of photons and exhibits behaviors like the photoelectric effect and Compton scattering.

Total internal reflection occurs when a light ray traveling from a denser medium to a rarer medium strikes the interface at an angle greater than the critical angle, causing the light to be completely reflected back into the denser medium. This phenomenon is utilized in optical fibers, prisms, and mirages.
