Strange question????

Post by markiver54 » Sat Dec 08, 2018 10:27 pm

Might be a strange ? ..I'm sitting inside my small home, back to the wall in dining room. Have a large mirror in the living room about 20 feet opposite. Snowing heavily outside right now, so just looking through the irons and optics in the house. Can I then assume that the POI is 40 feet away?

Off hand I would say that the P.O.I. is you.

LOL.. looking from slight angle...can't see myself. Just wondering if anyone ever used this method in short quarters. Probably warranted your answer. As I said...maybe a dumb question.

One physics review I read on viewing mirror images said "yes." Review had most interesting commentary both on distance and height of what you see.

I would have "guessed" the same answer, although physics (and especially chemistry) were not my top-notch subjects in school by a long shot! ;) A scientist I am not.

BTW, no such thing as a "strange ?" when you want to learn something, Mark.

No - you are aiming at the IMAGE in the mirror - which is only 20 ' away.
Therefore MY guess is POI is only 20'.

Yes.

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.

Dunno, but whatever you do, don't get tempted to pull the trigger. ;)
