Question

A monochromatic beam of light has a frequency v = 3 2 π × 10 12 Hz and is propagating along the direction i ^ + j ^ 2 . It is polarized along the k ^ direction. The acceptance form the magnetic field is:

TestHub · Accepted Answer

E ^ × B ^ should have given direction of wave propagation, ⇒ K ^ × B ^ ∥ i ^ + j ^ 2 K ^ × i ^ + j ^ 2 = j ^ - - i ^ 2 = i ^ + j ^ 2 ∥ i ^ + j ^ 2 . Wave propagation vector K ^ should be along i ^ + j ^ 2 .
