Activity 1
Refraction of light
Problem/Situation
1. A ray of light strikes the water surface of Lingayen Gulf at an angle of
incidence of 35
o
. Compute the angle of refraction if the index of refraction of
seawater is 1.33?
2. Ray of light traversing air enters another medium with an angle of incidence of 23o
and a refracted angle of 14o. What is the index of refraction of the unknown
medium?
