A glass plate with an index of refraction is 1.57 is immersed in an oil having a refractive index of 1.40.The surface of the glass is inclined at an angle of 54° with the vertical.A horizontal light ray in the glass strikes the interface.What is the angle that the refracted ray,in the oil,makes with the horizontal?
A)11°
B)5.6°
C)8.3°
D)14°
E)17°

Snell's law: n1*sin(theta1) = n2*sin(theta2)n1 = 1.57, n2 = 1.40, theta1 = 54°theta2 = sin^-1((n1*sin(theta1))/n2) = 11°
