Question

manish is standing in front of a plane mirror at a distance of 5feet.If he moves 2feet towards the mirror what will be the distance of his images from the mirror??

Answer 1

3 feet, as his distance from the mirror is 3 feet and we know that image formed in a  plane mirror is as behind in the mirror as the object is in front of it

Answer 2

$\textbf{ANSWER}$

$\textbf{TOPIC}$

Law of Reflection

$\textbf{ANSWER}$

3feet

$\textbf{REASON}$

According to law of Reflection the distance of an object from a plain mirror is equal to the distance of image from mirror

So ans is 3feet ( distance of object is same as image)

Now tell more about this type question

If we have find the distance of Manish from his image then ans is

6feet

$\textbf{EXPLANATION}$

First distance of Manish=5feet

so, it's image distance is also= 5feet

On changing his position

Manish move 2feet towards plane mirror

Distance of Manish from plane mirror=5-2=3ft

so, distance of Manish image from mirror= 3 ft

$\textbf{distance of Manish from his image}$

=distance of Manish from plane mirror + distance of Manish image from plane mirror

= 3feet+3feet

=(3+3)feet

=6feet

HENCE

distance of image from mirror= 3 feet

Distance of Manish from his image is 6 feet
