Marks: +1, -0

A converging lens of focal length 20 cm and refractive index

is coaxially placed in front of a convex mirror offocal length 5 cm. Their separation is d. A parallel beam of light incident on the lens returns as a parallel beamfrom the arrangement. Select the correct option(s)

The beam diameters of the incident and reflected beams must be the same
Value of d can be 10 cm
Value of d can be 20 cm
If the entire arrangement is immersed in water of refractive index
4
3
, then the path followed by incident beamremains unaltered
