An object is placed at a distance of 12 cm in front of a concave mirror of radius of curvature 30 cm. List our characterisitic of the image formed by the mirror

Explanation

Here, `u= - 12cm, R= - 30cm`, `f=R/2= -15 cm`
`(1)/(v)=(1)/(f) - 1/u =1/-15 +1/12=1/60`
`v=60cm`
The image is virtual, erect, magnified and is formed at the back of the mirror.
