Question

An object is placed at a distance of 60 cm fronm a concave mirror of focal length 30 cm. (i) find distance of image (ii) list 4 characteristics of image formed and draw ray diagram.

Answer 1

HEY MATE HERE IS YOUR ANSWER:

We are given

$(i)u = - 60cm \\ f = - 30cm \\ v = x \\ \frac{1}{u} + \frac{1}{v} = \frac{1}{f} \\ \frac{1}{x} = - \frac{ 1}{30} + \frac{1}{60} \\ \frac{1}{x} = - \frac{2}{60} + \frac{1}{60} \\ \frac{1}{x} = - \frac{1}{60} \\ x = - 60cm$

(ii) The four characteristics of the image formed are:

a. The image is real and inverted.

b. The image is formed in front of the mirror.

c. The image is of same size as the object.

d. The image is formed at centre of curvature.
