4. ### A light ray is travelling .The refractive index of XandY are 1and1.24.If the angle of incidence is 14°, find the angle of refraction (in °).?

(sin i) / (sin r) = (RI of Y) / (RI of X) = 1.24 / 1 = 1.24 sin r = (sin i) / 1.24 = (sin 14°) / 1.24 = 0.244 / 1.24 = 0.197 r = arcsin 0.107 = 11.36° (ans)
