Science question reflection and refraction are similar to each other. which one of the following is associated with only refraction? a) the light wave changes direction. b) the light wave keeps the same wavelength. c) the light wave is transmitted through the medium.

The answer is:

A) Light wave changes direction.

Here is why:

In refraction, the light bends or changes direction when it passes through one medium to another. The change happens because the speed of light is different depending on the medium it passes through because the density of the medium is different.

Another difference would be the angle of incidence. In reflection the angle of incidence is equal to the angle of reflection but in refraction, they are not the same.
