Question

Refractive indices of water and glass are 4/3 and 3/2 respectively. a light ray travelling in wateris incident on glass-water interface at 30°, the angle of sine of angle of reflection

Answer 1

Hi...

In case of refraction. It will follow Snell's law :-
sin i sin r= μglassμwater ........(1)

put sin i= sin 30o =1/2
put given values in eq (1), we get :-
(Angle of refraction) r = sin-1(4/9)..

Hope this helps u!!
