An orange light ray and a green light ray pass from an acrylic block to air with the same angle of incidence of 45^o . The orange is less deflected because:

(1) the index of refraction in acrylic for green light is greater than that of orange.

(2) the index of refraction in acrylic for green light is less than that of orange.

(3) the indices of refraction of both colors are greater in air than in acrylic.

(4). the indices of refraction of both colors are greater in acrylic than in air.
