A concave mirror cannot from

A

virtual image of virtual object

B

virtual image of real object

C

real imge of real object

D

real image of virtual object

Text Solution

Verified by Experts

The correct Answer is:
A
`1/v+1/u=1/f ...(i)`
For virtual object u is positive and for concave mirror f is negative,
Substituting these signs in Eq, (i), We can see that v is always megative or image is always real.
