Answer 1

Solution angile of moidence polarized Brewster's angile is on at which the light is reflected from the surface is perfectly Angle is given by OB De acc atan (na "a sufrenchive index of first medium There air m₂ = 1] Na refractive index of second medium Here ethanal n = 1.361. arc tan (1.361 mi 1 OB 53.69 1 1) OB = 53.690 % 53.7% So, angle is 53.70
