Question 29
PHMCQ2 marksNeeds review
An electromagnetic wave having electric field
is incident at
(normal incidence) on a square slab from vacuum (with refractive index
) as shown in the figure. The slab is composed of two different materials with refractive indices
and
. Assume that the permeability of each medium is the same. After passing through the slab for the first time, the electric field amplitude, in
, of the electromagnetic wave, which emerges from the slab in region 2, is closest to
