Violet light and red light travel through air and strike ablock of plastic at the same angle of incidence. The angle ofrefraction is 30.800° for the violet light and 31.280° forthe red light. The index of refraction for violet light in plasticis greater than that for red light by 0.0450. Delaying any roundingoff of calculations until the very end, find the index of refraction for violet light in plastic.
