Question

Identify the nature of mirror and mention two characteristics of image
formed when magnification m = + 6.

Answer 1

given m=+6
Positive sign indicates that image is virtual and erect
Number 6 indicates that the image is magnified.

So the nature of the mirror is concave mirror.

In concave mirror when object is placed in between P and F, we get image behind the mirror .
Nature of image:
---> Virtual and erect
----> Enlarged.
