Explanation / Answer

here,

angle of incidence, (Theta)a = 56 degrees

index of refraction of air, na = 1

index of refraction of air, nw = 1.3

Part a:
From snell's law :
na * Sin(Theta)a = nw * Sin(Theta)w

(theta)w = arcSin( (na/nw) * Sin(Theta)a )

Part B:
(theta)w = arcSin( (na/nw) * Sin(Theta)a )
(theta)w = arcSin( (1/1.33) * Sin(56) )
(theta)w = 38.56 degrees
