Question

32.The angle of incidence for a ray of light at a
refracting surface of a prism is 45°. The angle of
prism is 60°. If the ray suffers minimum deviation
through the prism, the angle of minimum deviation
and refractive index of the material of the prism
respectively, are :
(1) 45°, 1/√2
(2) 30°, V2
(3) 45°, 2
(4) 30°, 1/√2​

Answer 1

(2) 30°;√2

mark it as branliest

Answer 2

Answer:

30°,√2

Explanation:

as R.I is equal to sin i divide by sin r and r is A/2

So sin 45 is 1/√2 and sin 30 is 1/2

so after dividing we get RI-√2
