Solve the problem using Snell's Law: $$\frac { \sin \theta _ { 1 } } { \sin \theta _ { 2 } } = \frac { v _ { 1 } } { v _ { 2 } }$$
-A light beam traveling through air makes an angle of incidence of $39 ^ { \circ }$ upon a second medium. The refracted beam makes an angle of refraction of $28 ^ { \circ }$. What is the index of refraction of the material of the second medium? Give the answer to two decimal places.
A) $0.47$
B) $0.75$
C) $0.63$
D) $1.34$

The index of refraction $n$ can be found using Snell's Law in the form $n_1 \sin \theta_1 = n_2 \sin \theta_2$. Given that air has an index of refraction $n_1$ close to 1, and using the given angles, solving for $n_2$ yields approximately 1.34.
