Explain The Change Of Direction Of Light During Refraction

231 Words1 Pages
The change of direction of the light during refraction is because of the differences of the speeds of the light in different parts of the light wave, and this only happens if the light ray is going towards the new medium at an angle. For example when moving from air to glass, as a part of the wave reaches the glass slows down, the other parts are still travelling fast, and this difference in the speeds causes the wave front to align more towards the edge of the glass, therefore the direction of the light will bends towards normal. When the direction of the light travels perpendicular to the new medium(thus on the normal line), the light will not refract/change direction, but will just slow down. This is because as all parts of the light wave
