If an object that stands 3 cm high is placed 12 cm in front of a plane mirror how far from the mirror is the image located explain your reasoning

distance of image = 12 cm

Explanation:

For plane mirror the perpendicular distance of object from the mirror must be same as that of perpendicular distance of image from the mirror

As we know here that object is 3 cm high

But the distance of object from mirror is 12 cm

So here the image will be virtual and it will form at 12 cm distance behind the mirror.

So here image will form behind the mirror at same distance that is the distance of object from the mirror.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
