Question

Multiple Choice 3. A ray of light coming through medium 1 strikes a boundary of medium 1 and medium 2 and enters medium 2 making an angle 60 degrees with the boundary. If refractive index of medium 2 and 1 are 1.56 and 1.24 respectively, what angle does the ray light make in medium 1 with respect to boundary? A) 51° B) 21° C) 45° D) 39°

Answer 1

Sol 1,24 ni n = 1.56 2 = 90-60 Griven Data 30° Using snell's low n, sind = n₂ sin Q₂ 1.24 Sino, = 1156 Sin 30° Sindi 0.629. Oi = 38.980 then angle does eray light in medium with respect to boundary = 90-38.98 - 5102 ✓51° Hence, option (151° is correct answer.
