For total internal reflection light should travel from optically denser medium to optically rarer medium but during glass slab activity in ur video , light ray travelled from air to glass slab which is optically rarer to optically denser it doesn't satisfy above for total int. reflection why?

[@DeepthiS]

TIR doesn't happen in the case of glass slab.. only a lateral shift takes place...

Sir your way of explaination is very good, but you told wrong. 1.For glass as denser med. total internal reflection occurs inside the glass i.e. TIR OCCURS INSIDE THE DENSER MEDIUM 2. Then in your diagram hot air is denser than very hot air, so TIR should occur inside the denser medium i.e. inside hot air, but it is occurring inside a rarer medium i.e. very hot air. BUT THIS IS NOT POSSIBLE can you give a better explaination about this?

Sir, when air is hot it should be more dense since it has more humidity hot layer, but u r saying it should be rarer medium? Can u explain??

[@dr.pulakkole2389]

VY Comedy when air is heated it expands so the no. of molecules in a unit volume is low thus density is low
