2. If Suzie stands 3 feet in front of a plane mirror, how far from the person will her image be located?
Answer = 6 feet
Suzie (the object) is located 3 feet from the mirror. Suzie's image will be located 3 feet behind the mirror. Thus, the distance between Suzie and the image will be 6 feet.

A different science site than I looked at earlier today, but quite an interesting answer. Probably a good physics exam word problem, with the additional Qs to the students: "Why is this so? What proofs can you provide for a "Yes" answer?
For sure, I'd flunk this science exam.

True enough, though in the science of physics, that is described as a "virtual image" and is said to be located "behind" the mirror.Mags wrote:.
Suzie's image isn't 3 ft behind the mirror. Suzie is 3ft from the mirror. Her reflected image image is 3 ft from her eyes. Light off of Suzie travels to the mirror and back to her eyes.
https://www.physicsclassroom.com wrote: Virtual vs. Real Images
In the case of plane mirrors, the image is said to be a virtual image. Virtual images are images that are formed in locations where light does not actually reach. Light does not actually pass through the location on the other side of the mirror; it only appears to an observer as though the light is coming from this location. Whenever a mirror (whether a plane mirror or otherwise) creates an image that is virtual, it will be located behind the mirror where light does not really come from.
Keeps us all interested, and 'tis fun!markiver54 wrote:BTW.. thank you PT7. I might have more possibly strange questions in the future.

That's a good thing! Anyway, not the same quality mirror I originally mentioned but the thought did come to mind when looking through my sights. Actually...don't really like looking in the mirror at all anymore!
