Question
Two refracting media are separated by a spherical interface as shown in the figure. 
is the principal axis, 
and 
are the refractive indices of medium of incidence and medium of refraction respectively. Then :
- if
then there cannot be a real image of real object. - if , then there cannot be a real image of virtual abject.
- if , then there can be a virtual image of virtual object.
- if , then there cannot be a real image of real object.
then there cannot be a real image of real object. , then there cannot be a real image of virtual abject. then there can be a virtual image of virtual object., then there cannot be a real image of real object.The correct answer is: if then there cannot be a real image of real object.

In the diagram shown, a ray of light is incident on the interface between 1 and 2 at angle slightly greater than critical angle. The light suffers total internal reflection at this interface. After that the light ray falls at the interface of 1 and 3, and again it suffers total internal reflection. Which of the following relations should hold true?
