JEE MainPhysicsWave OpticsMCQ+4 / −1
Consider a tank made of glass(refractive index 1.5) with a thick bottom. It is filled with a liquid of refractive index μ\muμ. 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\muμ is : JEE Main 2019 (Online) 9th January Morning Slot Physics - Wave Optics Question 125 English
