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 is for a beam of light entering the liquid, the light reflected from the glass interface is never completely polarised. For this to happen, the minimum value of μ is - √5 /√3
- 3/√5
- 5/√3
- 4/3
plz explain also
