Question

During refraction, what happens to a wave when it travels from one medium to another?

Answer 1

Refraction is the change in direction of waves that occurs when waves travel from one medium to another. Refraction is always accompanied by a wavelength and speed change. Diffraction is the bending of waves around obstacles and openings.

Answer 2

Wave changes speed and direction.

Step-by-step explanation:

Refraction is simply the behavior attributed by waves, it could light or sound waves.

When refraction occurs, the wave changes speed when it moves from one medium to another. This makes the wave to change direction and therefore appear on the other side of the medium.
