A ray of light falls on a glass slab of refractive index u.if the reflected and refracted rays are mutually perpendicular to each other,find the angle of incidence.
Ans) let i be angle of incidence then angle of reflection is i ,by snell law sin i=usin r90-i+90-r=90i+r=90putting in above eqn.u= tan i
