In case of polarisation, if i is angle of incidence and θP is polarising angle then
In case of polarisation, if i is angle of incidence and θP is polarising angle then
- For i = θP, reflected light is fully polarised
- Both (2) and (3) are correct (correct)
- For i = θP, refracted and reflected light rays are perpendicular to each other
- For i = θP, refracted light is fully polarised
