Question

Find Brewster’s angle for light reflected from the top of a glass coffee table.

Answer 1

Question is supposed to be incomplete. Still giving you the formula for the above problem. Solve accordingly

Since light reflected from the coffee table is completely polarised parallel to the surface of the glass,

so, the angle of incidence = Brewster angle

Using Brewster's law, we have
                             

tan ?_B = n₂ / n₁

Where, n₁ and n₂ are refractive index of mediums

Comment in case any doubt, would be happy to help you, good luck...
