An object is placed 40 cm in front of a convex mirror of radius of curvature 20 cm. The image

Is real and 8 cm behind the mirror

Is real and 8 cm in front of the mirror

Is virtual and 8 cm in front of the mirror

Is virtual and 8 cm behind the mirror

Text Solution

Verified by Experts

The correct Answer is:

From mirror equation,
`1/f =1/u +1/v`
`1/10 =(-1)/40 +1/v`
v =50= 8 cm
`therefore` The image is virtual and 8 cm behind the minor.
