Light rays that hit the surface of a block of Plexiglas are bent, or refracted, according to Snell's Law:
N1sin 1 = n2sin 2.
Find the angle of refraction 2 of Plexiglas if its refraction index n2 = 1.51, the refraction index of air n1 = 1, and light enters the Plexiglas at an angle ?1 = 53°. Round your answer to 1 decimal place.
A) 56.9°
B) 31.9°
C) 58.1°
