web.mit.eduSince light is described by a transverse wave, there are two possible orthogonal direc-tions for the E~ vector in a plane normal to the propagation direction and these directions determine the polarization of the light. For cubic materials, the index of refraction is the same along the two transverse directions.

ocw.mit.eduA photon (quantum of light) is reflected from a mirror. (A) Because a photon has a zero mass, it does not exert a force on the mirror. (B) Although the photon has energy, it cannot transfer any energy to the surface because it has zero mass. (C) The photon carries momentum, and when it reflects off the mirror, it undergoes a change in
