Blocks of two different transparent materials are sitting in air and have identical light rays of the same wavelength incident on them at the same angle. Examining the figure, what can you say about the speed of light in these two blocks?
a) The speed of light is the same in both blocks.
b) The speed of light is greater in the block on thelleft.
c) The speed of light is greater in the block on the right.
d) The relative speed of light in the two blocks cannot be determined from the information given.
