## Homework Statement

The index of refraction for a diamond 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 30.0 degrees. Find the angles of refraction for these two colors.

## Homework Equations

n

_{1}sin

_{angle of incidence}= n

_{2}sin

_{angle of refraction}

## The Attempt at a Solution

I'm assuming that I use Snell's law, to find the two angles of refraction. I'm not sure if this is the right formula to use, however.

First, I changed the formula to be:

sin

_{angle of refraction}=n

_{1}sin

_{angle of incidence}/n

_{2}

Sin (r) = (2.410 x sin30)/(2.450)

=29.5 degrees for blue

and the second:

sin (r) = (2.450 x sin30)/(2.410)

=30.6 degrees for red

I don't know if this was the right way to do it... And I'm not sure if I attached the right color refraction to the right angle for the answers...
