The refracting angle of the prismis`60^(@)`.What is the angle of incidence for minimum deviation?The refractive index of material of prism is`sqrt(2)`.

Text Solution

Verified by Experts

For minimum deviation
`r=A//2=60//2=30^(@)`
From snell's law`(sin i)/(sin r)=mu or sqrt(2)=(sin i)/(sin 30^(@))`
`:.sin i =(1)/(2)xxsqrt(2)=(1)/(sqrt(2))=sin 45^(@)`or`i=45^(@)`
