Question

An object is placed at a distance of 30 cm in front of a convex mirror of focal length 15 cm. Write four characteristics of the image formed by the mirror.

Answer 1

Here, `u= -30 cm, f= 15cm`
From `(1)/(v) = (1)/(f) - 1/u = (1)/(15) - (1)/(-30) = (3)/(30) = 1/10`
`v = 10cm`.
The image is virtual, erect, smaller in size and at a distance of `10 cm` from the pole of the mirror at the back of the mirror.
