Once the light has crossed the boundary between the two media, it continues to travel in a straight line. This app is a sort of tutorial which explains the reflection and the refraction of waves by the principle of Huygens. When light traveling in one medium is incident on a thin film of material that is in contact with another medium, some light reflects off the front surface of the film, and some light goes through the film, reflects off the back surface of the film, and emerges back into the original medium. When light passes from one medium to another, some of this light is reflected while another part penetrates into the medium with a change in its direction. The index of refraction is a function of frequency. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
