Dispersion light

    1. The problem statement, all variables and given/known data

    A red beam of light in air enters crown glass at an angle of 60.00 to the normal.
    Find the angleof refraction.
    Repeat for a violet beam oflight entering crown glass (same angle).
    2. Relevant equations
    Not too sure, I believe I would use Snells law here.. does that sound correct?

    3. The attempt at a solution

    do not have an attempt because I do not know which equations to use.

    Yes, the relevant equation is Snell's Law. You also need to look up the refractive index of crown glass at different optical wavelengths (the two colors you are given).
