A thin prism of angle `A=6^(@)` produces a deviation `d=3^(@)`. Find the refractive index of the material of prism.

Text Solution

Verified by Experts

We know that `d=A(mu-1)` or `mu=1+(delta)/(A)`
Here, `A= 6^(@), d_(min)=30^(@)`
`mu=sin((60+30)/(2))/sin((60)/(2))=(sin45^(@))/(sin30^(@))=sqrt(2)=1.41`
