Question

For magnification in spherical mirrors object height is :

• A. Negative.
• B. Positive.
• C. For real images positive.
• D. For virtual images negative.

Answer 1

The correct option is B Positive.

Magnification is the ratio of image size produced by spherical mirrors to the object size. It is the ratio of the height of the image to the height of the object. The height of the object is always positive as the object is always above the principal axis.
