Question

A ray of light traveling in air strikes the surface of water at an angle of incidence of 35 degrees. Calculate the angle of refraction of the light in water. Index of refraction of water is 1.33, while that for air is 1.00.

Remember to identify all of your data, write the equation, and show your work.

Answer 1

Snell's law:

n1 sin (theta1) = n2 sin (theta2)

They ask you to solve for the outgoing angle--the angle of refraction:

theta2 = arcsine (n1 sin(theta1) / n2)

They give you the incident angle, theta1, the incident index, n1, and the outgoing index, n2.  Plugnchug.
