Question

Assume a person is standing in front of a plane mirror. The distance between the mirror and his image is 6m. If the person moves 2m towards the plane mirror, what would be the distance between the person and his image?​

Answer 1

Given :-

Distance between mirror and image is 6m

To find

The distance between the person and his image when he moves 2m towards the mirror

Solution :-

Case I

When the distance between image and mirror = 6cm

distance between person and mirror = 6m

•°• The distance between person and his image = 6+6= 12m

Case II

When person moves 2m towards the mirror

So it's image also moves 2m towards the mirror

•°• Total distance moved = 4m

So , the distance between person and his image = 12-4=8m

The distance between person and his image is 8m

Answer 2

Answer:

Given :-

Assume a person is standing in front of a plane mirror. The distance between the mirror and his image is 6m. If the person moves 2m towards the plane mirror

To Find :-

what would be the distance between the person and his image?

Solution :-

At first the distance between man and mirror is 6 m. Then again the distance increase by 6 m. Now,

When person move towards the mirror by 2 m

So,

At first add both distance and subtract them by 2

$\large \sf \bigg \lgroup \: 6 + 6 \bigg \rgroup - 2$

$\large \sf \: 10 - 2$

$\large \sf \: 8 \: m$

Thus, The distance between person and image is 8 m.
