Question

Write down a formula for the magnification produced by a concave mirror.; (a) in terms of height of object and height of image; (b) in terms of object distance and image distance

Answer 1

Explanation:

here the formula is given below..the magnification of concave mirror is

m=-v/u

means magnification is equal to height of image /height of object

Answer 2

Answer:

(a) magnification produced by a concave mirror in terms of the height of the object and height of the image is   $\frac{h_i}{h_o}$.

(b) magnification produced by a concave mirror in terms of object distance and image distance is v/u.

Explanation:

Magnification: It is the process of enlarging the image formed from the object by using some optical instruments.

(a) Magnification of concave mirror in terms of the height of object and height of the image is given by:

$m = \frac{h_i}{h_o}$

Where $h_i$ is the height of the image, $h_o$ is the height of the object, and m is the magnification of the concave mirror.

(b) Magnification of concave mirror in terms of the object distance and image distance is given by:

$m = -\frac{v}{u}$

Where v is the distance between the mirror and the image formed by it, u is the distance between the mirror and the object placed in front of the mirror, and m is the magnification of the concave mirror.
