Question

Justify the statement: “Total internal reflection is the phenomenon where there is NO partial reflection or refraction.”

Answer 1

Hi...
Total internal reflection(T.I.R) is the phenomenon which occurs when a propagated wave strikes a medium boundary at an angle larger than a particular critical angle with respect to the normal to the surface. If the refractive index is lower on the other side of the boundary and the incident angle is greater than the critical angle, the wave cannot pass through and is entirely reflected..


Hope this helps u!!
