Problem 33P
A beam of light in air strikes a slab of glass (n = 1.52) and is partially reflected and partially refracted. Find the angle of incidence if the angle of reflection is twice the angle of refraction.
ANSWER:
Step 1 of 3
In reflection, the angle of incidence will be equal to the angle of reflection by the law of reflection. i.e., .
Since, the angle of reflection is twice of angle of refraction then the angle of incidence will also be twice of angle of refraction. i.e.,.
The equation for the angle of refraction by using Snell's law is as follows:
