Wave changes direction at surface, returns to same medium
Angle of incidence = angle of reflection (from normal)
Wave bends entering new medium due to speed change
n=cvn = \frac{c}{v}n=vc (c=vacuum speed, v=medium speed)
n1sinθ1=n2sinθ2n_1 \sin \theta_1 = n_2 \sin \theta_2n1sinθ1=n2sinθ2
sinθc=n2n1\sin \theta_c = \frac{n_2}{n_1}sinθc=n1n2 where n1>n2n_1 > n_2n1>n2
Bends toward the normal
High to low n, angle ≥ critical angle
c=3.00×108c = 3.00 \times 10^8c=3.00×108 m/s
