Question

define the magnification of mirrors? what does positive and negative magnification indicates? write the formula of magnification for spherical mirrors​

Answer 1

Answer:

It is the ratio of the height of the image to the height of the object and is denoted as m. The magnification, m produced by a spherical mirror can be expressed as: m=h′h where h′ is height of image and h is height of object. It is also equal to the negative of the ratio of the image distance(v) to object distance (u)
