Solve the Problem sinθ1sinθ2=v1v2\frac { \sin \theta _ { 1 } } { \sin \theta _ { 2 } } = \frac { \mathrm { v } _ { 1 } } { \mathrm { v } _ { 2 } }

Question 5

Multiple Choice

Solve the problem.
-Snell's Law states that sinθ1sinθ2=v1v2\frac { \sin \theta _ { 1 } } { \sin \theta _ { 2 } } = \frac { \mathrm { v } _ { 1 } } { \mathrm { v } _ { 2 } }
where v1,v2v _ { 1 } , v _ { 2 } are the speeds at which light travels through two different mediums, and θ1,θ2\theta _ { 1 } , \theta _ { 2 } are the angles of incidence and refraction respectively. Find the angle of refraction if v1v2=1.6\frac { \mathrm { v } _ { 1 } } { \mathrm { v } _ { 2 } } = 1.6 and the angle of incidence is 2626 ^ { \circ } . Give your answer in degrees to the nearest hundredth.


A) 15.9015.90 ^ { \circ }
B) 5.245.24 ^ { \circ }
C) 7.877.87 ^ { \circ }
