A light wave is incident normally on a glass slab of refractive index 1.5. If 4% of light gets reflected and the amplitude of the electric field of the incident light is 30 V/m, then the amplitude of the electric field for the wave propagating in the glass medium will be:
(A) 30 V/m
(B) 10 V/m
(C) 24 V/m
(D) 6 V/m
