Question

A light wave moves from diamond (n = 2.1) into water (n = 1.83) at an angle of 19°. What angle does it have in water?

Answer 1

θ = 0.3736

Step-by-step explanation:

For this exercise, how light passes through two media separated by a distance, so its movement is governed by the law of refraction.

n₁ sin 19 = n₂ sint θ

let's use subscript 1 for diamond and sub start 2 for water

sin θo = n₁ / n₂ sin θ

sin θ =
`(2.1)/(1.83)` sin 19 0.325 56

θ = 0.3736
