Red light (n = 1.520) and violet light (n = 1.538) traveling in air are incident on a slab of crown glass. Both colors enter the glass at the same angle of refraction. The red light has an angle of incidence of 26.50°. What is the angle of incidence of the violet light?

snells law
sin Incidence= n*sinrefraction

so, then
1= nred/nviolet * sin26.5/sinTheta
