Question

the basic cause of refraction is​

Answer 1

Answer:

The basic cause of refraction is speed.

Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction.

Hope this helps you.
