Quiz – Snell’s Law
(a)
(c) Refracted ray
(e) Angle of refraction
(d) Angle of incidence
(b) Incident ray
A fish is underwater. A girl in a boat looks through the water to see the fish. The incident light rays from the fish strike the surface of the water with an angle of incidence of 30°.
a. Draw a line normal to the surface of the water that intersects the light path.
b. Label the incident ray.
c. Label the refracted ray.
d. Label the angle of incidence.
e. Label the angle of refraction.
f. Find the angle of refraction.
Index of refraction of water: 1.333
Index of refraction of air: 1.0
