Answer» Thus the value of angle of refraction is 29.1°Explanation:We are given data:REFRACTIVE index of glass = 1.52Refractive index of WATER = 1.32Angle of incidence "i" = 25°To FIND: Angle of refraction "r" = ?SOLUTION:Using Snell's LAW:n1 ( Glass) = 1.52n2 (Water) = 1.32n1 sin (i) = n2 sin t1.52 sin (25°) = 1.32 sin rr = [arc sin (1.52 / 1.32) sin 25° ]r = 29.1°Thus the value of angle of refraction is 29.1°
