Question

Write magnification of a mirror, and explain terms in it

Answer 1

Answer:

The ratio of the height of the image to that of the object is called linear magnification or transverse magnification or just magnification. It is denoted by m. An object 5.0 cm in length is placed at a distance of 20 cm in front of a convex mirror of radius of curvature 30 cm

Answer 2

Answer:

Here, h is the height of image and h' is the height of the object. Magnification is also equal to the ratio of image distance to the object distance. As the object is always above the principal axis, the height of the object is always positive.
