If the polarizing angle of a piece of glass for green light is 54.74^ , then the angle of minimum deviation for an equilateral prism made of same glass is (Given : tan ⁡54.74^ =1.414 )

Question

Accepted Answer

Correct answer: D. (d) : = tan ⁡i_p= tan ⁡54.74^ =1.414= 2 = sin ⁡ ( (A+ _m)2 ) sin ⁡ A2= 2 sin ⁡ ( 60^ + _m2 )= 2 sin ⁡ 60^ 2= 2 12= 1 2 or sin ⁡ ( 60^ + _m2 )= sin ⁡45^ or 60^ + _m2=45^ or _m=90^ -60^ =30^

$If the polarizing angle of a piece of glass for green light is 54.74^{\circ}, then the angle of minimum deviation for an equilateral prism made of same glass is (Given : tan 54.74^{\circ} = 1.414)$
