W.k.t light gets polarised when incident from rarer to denser medium.(gets polarised by reflection at a certain angle ie: angle of polarisation) But if the light is sent from a denser medium to rare mediym, will there be any polarisation?? If there is, will it be due to reflection?? And can the angle of polarisation become equal to critical angle in that case, leading to total internal teflection?? Ultimately my doubt is that can light be polarised by 'total internal reflection??'
