Question

A concave mirror has a radius of curvature of 24 cm. If the object is placed 20 cm in front of the mirror then determine the properties of the image.

A. Real, upright and enlarged

B. Real, inverted and enlarged

C. Virtual, upright and enlarged

D. Virtual, inverted and smaller

Its MCQ​

Answer 1

The correct awnser is ସି)

First of all,

Object distance=20 cm

Radius of curvature=24cm=R

Therefore,

(2/R)=(1/f)

f=12cm

Then,

(1/u)+(1/v)=(1/f). [Put value, calculate]

=>v=30cm.

Linear magnification=h=v/u=30/20=3/2=1.5

Therefore,

Image is virtual(due to concave mirror), upright(because v has a positive sign) and magnified(due to linear magnification, being more that 1).

Hope you get it,

Best of Luck.
