Question

The figure attached to this problem depicts light incident at an angle of 35 degrees on a boundary between two transparent materials. Some of the light travels down through the next three materials, while some of it reflects upward and the escaped into the air. If n1= 1.2, n2=1.35, n3= 1.30, and n4 = 1.48. Find θ₄, the transmission angle into the last material.

• A. 35.0 degrees

• B. 27.7 degrees

• C. 55.7 degrees

• D. 60.7 degrees
