An equilateral prism is made up of material of refractive index sqrt3. The angle of minimum deviation of light passing through the prism is ________.

Answer»


SOLUTION :HINT `n=SQRT3=(SIN""(A+D_(m))/(2))/(sin""(A)/(2))=(sin""(60^(@)+D_(m))/(2))/(sin 30^(@))`
`rArr sin((60^(@)+D_(m))/(2))=sqrt3.sin30^(@)=(sqrt3)/(2) or (60^(@)+D_(m))/(2)=sin^(-1)((sqrt3)/(2))=60^(@)`
`rArr D_(m)=60^(@)`
