Explanation / Answer

here,

for medium A,

refractive index , n1 = 1.25

angle with normal , theta 1 = 51 degree

for medium B,

refractive index , n2 = 1.66

let the angle with normal be theta2

using snell's law

sin(theta1)/sin(theta2) = n2 / n1

sin(51) / sin(theta2) = 1.66 / 1.25

theta 2 = 35.8 degree

the angle of ray 2 with normal in medium B is 35.8 degree

(2)

for medium A,

refractive index , n1 = 1.25

let the angle with normal be theta1

for medium B,

refractive index , n2 = 1.66

angle with normal = 35.8 degree

using snell's law

sin(theta1)/sin(theta2) = n2 / n1

sin(theta 1) / sin(35.8) = 1.66 / 1.25

theta 2 = 51 degree

the angle of ray 2 with normal in medium A is 51 degree
