The angle of polarisation on a certain crystal is `55^(@)C`. The reflected light is completely polarised. Find the refractive index of the crystal andangle of refraction.

Text Solution

Verified by Experts

Refractive index, `n=tan theta_(p)=tan 55^(@)=1.428`
`r +theta_(P)=90" " :. R-90-theta_(P)=90-55=35^(@)`
