Define critical angle for total internal reflection.

Material A has critical angle i_(A) , and material B has critical angle i_(B)(i_(B)gti_(A)) . Then which of the following is true (i) Light can be totally internally reflected when it passes from B to A (ii) Light can be totally internally relected when it passes from A to B (iii) Critical angle for total internal reflection is i_(B)-i_(A) (iv) Critical angle between A and B is sin^(-1)((sini_(A))/(sin i_(B)))
