A light wave has a 670 nm wavelength in air. Its wavelength in a transparent solid is 376 nm.
(a) What is the speed of light in this solid?
(b) What is the light's frequency in the solid?
3*10^8 * (376/670)
There is no mechanism for the waves standing stationary in line waiting to get into your plastic stuff. Therefore the same number per second go by a spot inside as go by outside.
I am struggling trying to figure the frequency. Thanks for the help with part a.
