Question
A converging lens of focal length f1 is placed in front of and coaxial with a convex with a convex mirror of focal length f2. Their separation is d. A parallel beam of light incident on the lens returns as a parallel beam from the the arrangement -
Options
A.The beam diameters of the incident and reflected beams must be the same
B.d = | f1 | - 2 | f2 |
C.d = | f1 | - | f2 |
D.If the entire arrangement is immersed in water, the conditions will remain unaltered
