Refraction through a prism

By in IIT JEE, Interesting Questions, Optics on .

For an equilateral prism , find two angle of incidence differing by 20 degrees showing same deviation of 40 degrees?

Asked Atambir Singh

Answer:

Use the formula \delta =i_{1}+i_{2}-A

Here A = 60 degree (Since equilateral prism)

deviation is 40 degree

This gives A+\delta =i_{1}+i_{2}=100

Therefore,

the values of angles of incidence are 60 degree and 40 degree
