| September 18, 2021 | education
Parallel rays of light pass from air to water. The angle of incidence of the rays is 55 degrees. Determine the angle of refraction of the rays. n = 1.33
Data: α (angle of incidence of the indicated rays) = 55º; n (relative refractive index) = 1.33.
The angle of refraction of the indicated rays is calculated using the formula: n = sinα / sinγ, whence we express: γ = arcsin (sinα / n) = arcsin (sin 55º / 1.33) = 38º.
Answer: The angle of refraction of these rays is 38º.
