What is the angle of refraction when a ray of light passes from ethanol to air if the incident angle is 34°? The refractive index of ethanol is 1.36 and of air is 1.00.

A. 21

B. 34

C. 49

D. 66

This problem can be solved using Snell's law: " n1 * sin theta1 = n2 * sin theta2"

Given:

n1 = 1.36

theta1 = 34 degrees

n2 = 1.00

theta2 = ?

1.36 * sin (34) = 1 * sin (theta2)

angle of refraction = 49.51 degrees

Among the choices, the correct answer is C.
