A diamond's index of refraction for red light, 656 nm is 2.410 while that for blue light, 434 nm, is 2.450. Suppose white light is incident on the diamond at 30 degrees. Find the angles of refraction for these two colors.

Answer 1

Use Snell's Law: n1sin(theta1)=n2sin(theta2)
Since white light is incident at 30degrees, theta1 = 30.

Calculate the angle of refraction for the blue and red lights separately. For each case, n1 should be the index of air while n2 is the index for the blue or red light of diamond.
