Snell's Law is especially important for optical devices, such as fiber optics.
Snell's Law states that the ratio of the sine of the angles of incidence and transmission is equal to the ratio of the refractive index of the materials at the interface.
Since the light is traveling from a rarer region (lower n) to a denser region (higher n) .
It will bend toward the normal.
We will identify air as medium 1 and the fiber as medium 2.
n1 = 1.00, n2 = 1.44, and θ/font>1 = 22o.
Snell's Law then becomes (1.00) sin 22o = 1.44 sin θ2.
