Question

2. In what coses dous a
light say not deviate
at be interface of two media ? (As)
$\gamma \beta \alpha \tan( \sin( \cos( \cot(\% \binom{\% log_{ log( \: how \: ) }(?) }{?} ) ) )what \: is the answer$
​

Answer 1

Answer:

if we observe that light is not deviating at the whole surfaces of the two media then there is two things possible .(1). the light is incident normally at the surface .(2). the refractive index of the two same mediums are same .
