Question

Q1. What is the nature and size of image of a mirror having linear magnification is +2? ​

Answer 1

Answer:

Linear magnification produced by a spherical mirror is the ratio of the size of the image formed by the mirror so that of the size of the object.

⇒ m=

O

I

where, I = Image size

And, O = Object size

Answer 2

Answer:

Linear magnification is given as Image size/ Object size

For calculations of magnification, values of image size and object size are taken with proper sign convention.

For an inverted image, the image size is taken as negative and hence magnification is negative.
