Investigate how the angle of refraction is affected by different inputs of the angle of incidence through a glass block.

... Physics Investigation I am going to investigate how the angle of refraction is affected by different inputs of the angle of incidence through a glass block. Background Information: When light goes from air to another transport material it slows down - only slightly, but enough to make it change direction or refract. Refraction can be explained using wave theory. As the light waves hit the boundary with the second material, they slow down. This causes a change of direction towards the "normal" as the light waves are "bunched up" (a shorter wavelength). When light passes back out into air, the refraction is away from the normal, because the light speeds up. Rays of light travelling from air into glass are bent or refracted towards the normal. Rays of light travelling from glass into air are refracted away from the normal. In other words the angle of refraction is less than the angle of
