Two monochromatic rays of light are incident normally on the face `AB` of an isosceles right-angled prism `ABC`. The refractive indices of the glass prism for the two rays `'1'` and `'2'` are respectively `1.38` and `1.52`. Trace the path of these rays after entering through the prism.

Explanation

(1) `mu_(1)=1.38`
for critical angle
`Sin C_(1)=1//mu_(1)`
`Sin C_(1)=1//1.38`
for both rays angle of incidence is `45^(@)`
`sin C_(1)=(1)/(1.38)` .
`C_(1)gt45^(@)(46.44^(@))`
Thus, second ray will go for `T.I.R.`
(2) `mu_(2)=1.52`
for critical angle
`Sin C_(2)=1//mu_(2)`
`Sin C_(2)=1//1.52`
`Sin C_(2)=(1)/(1.52)`
`C_(2)lt45^(@)(41-14^(@))`
