Question

5. An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. find
the position and nature of the image.
chemical conation?​

Answer 1

Given u = -10cm , v= ? , f = -15cm

Applying mirror's formula,1/v +1/u = 1/f

1/v + 1/-10 = 1/-15

1/v = -1/15 + 1/10

=(-2+3)/30

= 1/30

V = 30 cm.

Hence, we get enlarged image, virtual in nature having magnification 3.
