An object is placed at a distance of 40 cm in front of a convex mirror of radius of curvature 40 cm. List four characteristic of the image formed by the mirror.

Explanation

Here, u= -40 cm, `f= R//2 =40//2`=20cm.
`(1)/(v) =(1)/(f) - 1/u = 1/20 - 1/-40 = 3/40, v=40/3 cm`.
The image is virtual, erect , at the back of the mirror and smaller in size.
