water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.
These effects on light propagation occur because light travels at
different speeds depending on the medium. The index of refraction
of a material, denoted by n, gives an indication of the speed of...
