Answer 1

Answer:

Option (A)

Explanation:

According to question, reflected and refracted are perpendicular to each other. hence,

i + r = 90° ---- (1)

Now,

μ = (sin i/sin r)

=> √3 = (sin i/sin(90 - i))

=> √3 = sin i/cos I

=> √3 = tan I

=> i = 60°

Place i = 60° in (1), we get

=> r = 60°

Therefore,

Angle of refraction is 60°.
