A medium is what a wave moves through. • Ocean waves travel through water • Light waves can travel through empty space.
A light wave always travels in straight lines when it is moving through one medium.
Refraction is the bending of light as it moves from one medium to another.
Refraction
Why Does Refraction Happen? When light rays move between two mediums, the speed of light changes. • The change in the speed causes the light rays to bend.
