Question

Linear magnification is

• B. Negative for an erect image
• C. Zero for an inverted image
• D. Negative for an inverted image

Answer 1

The correct option is D Negative for an inverted image

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.
