Determine which medium the light beam is going into if the beam falls at an angle of 40 ° and refracts at an angle of 29 °.
| April 8, 2021 | education
Data: α (angle of incidence of the beam under consideration) = 40º; γ (reflection angle) = 29º.
The type of medium through which the light beam under consideration has passed can be determined by the relative refractive index: n = sinα / sinγ = sin 40º / sin 29º = 1.326 (water).
Answer: The beam of light in question has passed through the water.
