Light strikes a diamond (n = 2.42)immersed in glycerin (n = 1.473)at an angle of 60$\degree$ relative to the normal to the surface.What is the angle of refraction?
A)20$\degree$
B)60$\degree$
C)32$\degree$
D)64$\degree$
E)15$\degree$

Using Snell's law, we can calculate the angle of refraction:
n1sinθ1 = n2sinθ2
Here, n1 = 1 (since light is coming from air), θ1 = 60 degrees, n2 = 1.473 (glycerin's refractive index), and we need to find θ2.
Thus,
1sin60 = 1.473sinθ2
sinθ2 = (1sin60)/1.473 = 0.680
θ2 = sin^-1(0.680) = 32 degrees (approximately)
Therefore, the answer is choice C, 32 degrees.
