Question:medium

A ray of light is travelling from a medium of refractive index 1.414 to air. If the angle of incidence is $48^{\circ}$, then the angle of deviation of the light ray is

Show Hint

Always calculate the critical angle first when light travels from denser to rarer medium. If $i<C$, refraction occurs ($\delta = r - i$). If $i>C$, reflection occurs ($\delta = 180 - 2i$).
