1.	A light ray travelling in glass medium is incident of glass- air interface at an angle of incidence `theta`. The reflected `(R )` and transmitted (T) intensities, both as function of `theta`, are plotted The correct sketch isA. B. C. D.
Answer» Correct Answer - C When the light is incident on glass - an interface at an angle less than critical angle a small part of light will be reflected and most part will be transmitted. When the light is incident greater than the critical angle, it gets completed reflected (total internal reflection) These characteristics are depicted in option (c).
