Solve the Equation for Solutions Over the Interval [0 [0,2π)[ 0,2 \pi )

Question 139

Multiple Choice

Solve the equation for solutions over the interval [0, [0,2π) [ 0,2 \pi ) ) . Write solutions as exact values or to four decimal places, as
appropriate.
-Snell's Law states that
sinθ1sinθ2=v1v2\frac { \sin \theta _ { 1 } } { \sin \theta _ { 2 } } = \frac { \mathrm { v } _ { 1 } } { \mathrm { v } _ { 2 } }
where v1,v2\mathrm { v } _ { 1 } , \mathrm { 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=1.7\frac { { } ^ { v _ { 1 } } } { \mathrm { v } _ { 2 } } = 1.7 and the angle of incidence is 1414 ^ { \circ } . Give your answer in degrees to the nearest hundredth.


A) 2.722.72 ^ { \circ }
