Calculate the angle of minimum deviation for a ray which is refracted through an equiangular prism of refractive index 1.4
600
290
990
900
Correct answer is B
From the relation refractive index = Sin (A+Dm2)
Where A = refractive angle = 600, Sin(A2)
⟹1.4=Sin(600+Dm2)Sin(602)=Sin(60+Dm2)Sin300=Sin(60+Dm2)0.5Therefore1.4×0.5=Sin(60+Dm2)Therefore(60+Dm2)=Sin−10.7000=440121600+Dm=880241Dm=880241−600=28024290
