if light shines through a medium with a higher index of refraction than air why do the different wavelengths of light separate?

Answer:

Step-by-step explanation:

f light enters any substance with a higher refractive index (such as from air into glass) it slows down. The light bends towards the normal line. If light travels enters into a substance with a lower refractive index (such as from water into air) it speeds up. The light bends away from the normal line.
