Question

The magnification of convex mirror is given a place to if a chalk piece of height is 5cm is kept in front of the mirror what is the height of the image

Answer 1

Answer:

0.4 cm

Explanation:

M= hi/ho ; where hi= height of image

ho= height of object

M=magnification

Given: M=+2

ho= 5 cm

To find: height of image (hi)

M= hi/ho

2=hi/5

hi=2/5

hi=0.4 cm

So, height of image = 0.4 cm

Answer 2

Answer:

The height of the image will be five times the height of object = 5M

Explanation:

As per the data given in the question,

We have,

Height of object = 5 cm

Let the magnification given be M

As we know,

$Magnification = \frac{Hi}{Ho}\\ M=\frac{Hi}{5}\\ Hi=5M$

Hence,

The height of the image will be five times the height of object = 5M
