Answer #1

a) angle of Reflection is equal to the angle of incidence so Reflected light angle = 21-degree

b) To get the angle of refracted light we need the refractive index of Zircon (Since its not given, I assume it n2=1.95 ) and then apply Snells's law , n1Sin1 = n2Sin2 where n1=1 and 1=21  

Putting these value in the above equation , 2 = 10.58 degree
