The speed of light in a transparent plastic is 2.5x108 m/s. if a ray of light in air(with n-1) strikes this plastic at an angle of incidence of 31.3 degrees, find the angle of the transmitted ray. select one: a. 31.30 degrees b. 26.08 degrees c, 37.56 degrees d. 38.57 degrees e. 0.67 degrees

Angle of transmitted ray is

Explanation:

According to snell's law we have

Since the incident medium is air thus we have

By definition of refractive index we have

c = speed of light in vacuum

v = speed of light in medium

Applying values we get

Thus using the calculated values in Snell's law we obtain
