Answer 1

Question:-

An object 10 cm high is placed at a distance of 60cm in front of a concave mirror of focal length 20cm. Find the position and size of image by drawing the ray diagram.

Solution:-

Focal length of concave mirror, f = -20 cm

Distance of object from the mirror, u = -10 cm

use formula, 1/v + 1/u = 1/f

➭ or, 1/v = 1/f - 1/u

➭ or , 1/v = 1/-20 - 1/-60

➭ or, 1/v = -1/20 + 1/60

➭ or, 1/v = -2/60

Hence, image position is the 60cm right side from the pole of the concave mirror as shown in the diagram. The image is straight and bigger than the object.
