Refraction-Bending Light Water - index of refraction, n W = 1.33 Wave crests are closer together in higher index materials because the waves travel slower. Air - index of refraction, n A = 1.0 Think of rows in a marching band that slow down in a mud puddle.

Refraction-Bending Light Water - index of refraction, n W = 1.33 When light enters at an angle, it “bends.” Air - index of refraction, n A = 1.0 Think of rows in a marching band that slow down in mud puddle. Ray direction always perpendicular to the waves.
