Which direction is light bent when it passes from air to water?

Question

what about when it passes from water to air?

Answer 1

Snell' law says

n1 sin(q1) = n2 sin(q2) where n1, n2 are teh indicies of refraction of teh media the light is leaving and enerting respectively, and q1, q2 are the angles of incidence and refraction respectively. For air to water:

n1 = 1 < n2 Therefore sin(q2) < sin(q1) or q2
When going from water to air, the light is bent aeay from the normal line. The normal line is the line perpendicular to the surface of teh interface.
