A Thin Flashlight Beam Traveling in Air Strikes a Glass $52 ^ { \circ }$

A thin flashlight beam traveling in air strikes a glass plate at an angle of $52 ^ { \circ }$ with the plane of the surface of the plate. If the index of refraction of the glass is $1.4$ , what angle will the beam make with the normal in the glass?

A) $26 ^ { \circ }$
B) $38 ^ { \circ }$
C) $56 ^ { \circ }$
D) $34 ^ { \circ }$
E) $64 ^ { \circ }$
