Question

An object 5 cm high is placed in front of a convex mirror. If the magnification produced by the mirror is 0.5, the size of the image will be
(a) 2.5 cm
(b) 5 cm
(c) 10 cm
(d) 20 cm​

Answer 1

Answer:

The answer is (a) 2.5cm

Explanation:

We know that for a convex lens the magnification is given by:

Magnification = I/O

Where I = Size of image

O= Size of Object

As, Magnification = 0.5X

And O = 5cm

So,

0.5 = I/5

I = 0.5x5

Image Size = 2.5
