The bending of light as it moves from one medium to another with differing indices of refraction is due to a change in what property of the light?

Speed

Explanation:

The process whereby light bends as it moves from one medium to another (given that the two media have different indices of refraction) is called Refraction.

This process occurs due to the change in the speed of light as it changes media.

This change in speed is accompanied with a change in the wavelength of the light but the frequency remains constant.

The angle of refraction depends on the change in the speed of light and the angle of incidence of the object.
