Unpolarised light is incident on a plane glass surface. What should be the angle of incidence so that the reflected and refracted rays are perpendicular to each other?

according to Brewster’s law.... 
tanp= n    
(n=1.5)...................given
therefore tanp = 1.5
p=tan ^-1 (1.5)
p=56.3 degree 
hence the answer
