Question

1. The linear magnification of the image produced by a mirror is -2 cm. Find the size of the image if the size of the object is 1.5 cm. What is the nature of such an image!​

Answer 1

Answer:

3 cm, real and inverted

Explanation:

m = - 2 cm.

h = 1.5 cm   (object size)

h' = ?  (image size)

m = height of image/height of object = h'/h

-2 = h'/1.5

h' = 1.5 x -2  => -3

Size of image is 3 cm. Since it has a negative sign, it means image is inverted and real.

P.S : The mirror is concave.
