Problem

For a certain transparent material the refractive index for violet light is

1.02

times that for red light. A beam of white light from air strikes the surface at

45^{\circ}

. The red component is refracted at

30^{\circ}

. The approximate angle of refraction for the violet component is a)

31^{\circ}

29.4^{\circ}

30^{\circ}

28^{\circ}
