For what angle of incidence will light incident on a bucket filled with liquid having refractive index 1.5 be completely polarized after reflection |
|
Answer» ong>Explanation: CONSIDER a tank made of glass(refractive INDEX 1.5) with a thick bottom. It is filled with a liquid of refractive index μ. A STUDENT finds that, irrespective of what the incident angle i (see figure) is for a beam of light entering the liquid, the light reflected from the liquid glass interface is never completely POLARIZED. For this to HAPPEN, the minimum value of μ is |
