Question

A ray of light, travelling in a medium of refractive index μ, is incident at an angle i on a composite transparent plate consisting of three plates of refractive indices μ1,μ2 and μ3. The ray emerges from the composite plate into a medium of refractive index μ,, at angle x, Then


A
sin x=sin i

B
sin x=μμ,sin i

C
sin x=μ,μsin i

D
sin x=μ1μ2.μ3μ2sin i
loader

Solution

The correct option is B sin x=μμ,sin i


Applying Snell's law at point of incidence and point of emergence, we have

μ sin i=μsin x

sin x=μμsin i
