1avik now i will kill u :P :P :P
sir aap baar bar ye explain kar rahe hain ki internal reflection ho jata hai!!!but i have also seen in a lecture on rainbows ALONGWITH T.I.R. refraction too occurs.......n this seems something really weird to me...
as the usual thing i ever studied was tht when T.I.R taskes places at tht place no refraction should occur simualtaneously!

1@inovate........read what i have wrtitten carefully
am i an idiot???u guys r explaining me the same old thing LOL!
i know all that i m asking how the hell can refraction occurs simultaenously when the angle of incidence is greater than critical angle!
13I didn't get ur Qn exactly.
Frm the most basic ppoint of view...
TIR & Refraction both occur, but at different interfaces.
Fr Primary Rainbow- 2 Refractions (while entering & leaving the drop) & 1 TIR (inside drop).
Same way - 2 Refractions & 2 TIR(s) fr the secondary rainbow.
Otherwise, Before shouting at me fr the above, tell me wht the doubt exactly is ;)

ab see above figure got my question i saw tht in a video lecture.......n could not believe my eyes thts y i posted this question.........but most wanna be idiotic geniuses LOL!!
13Aah ok!
So, is tht white light....? Because each of its components will have its own Ref. Index which infers each specific wavelength having its own critical angle.
So, it can happen ki some wavelengths are reflected n some refracted.
