Respuesta :
D) The speed of a wave slows as it travels at different speed in different media.
The efraction of light wave occurs because the speed of a wave reduces as it travels at different speed in different media.
What is refraction of a wave?
Refraction of a wave is the bending of a wave as it travels between media of different densities.
Refraction of light waves usually occurs at the interface of the two media.
For the refraction of light, due to difference in the density between air and glass, the light waves will travel at a lesser velocity in glass than in air.
Therefore, the refraction of light occurs because the speed of a wave slows as it travels at different speed in different media.
