Snell's Law or the Law of Refraction describes the behavior of light as it travels between two
substances, telling us how light bends.
Snell's law tells us about the relationship be-
tween the angle of incidence, 01, and the angle
of refraction, 02, as a ray of light travels from one
medium to another and depends on the refrac-
tion indices n₁ and n₂ of both of the substance.

n₁ sin(01) = n2 sin (02)
(a) Which letters represent variables?
Air (1)

02
Glass (n2)
(b) Which letters represent constants?
d02
(c) (D9) Use Implicit differentiation to compute
d01
(d) The refraction index of air is n₁ = 1 and the refraction index of glass is n2 = 1.52. If the
angle of incidence is 0₁ = 20° verify that the angle of refraction is approximately 02 ≈ 13°.
(Make sure you calculator is in degrees mode, and just plug in numbers to verify the equation
balances.)
