quote:Originally posted by Solvay_1927Trevor,you're a physics teacher? Oh goody, someone who can answer all our questions! I like the mirror question - I've never thought about it that way before. In fact, it's so good it prompted me to spend ages searching the web for an answer.It turns out it's a fairly well known question, with lots of web links attempting to answer it - mostly with punny titles like "Some reflections on the mirror problem" (oh dear, oh dear). But it's hard to find a single, definitive, definitely "correct" answer.The best (in my opinion) three sites that I've found are as follows. Problem is, they're all a bit long. The first link below is probably the easiest to read. The first paragraph of the second link is useful too.http://www.redrice.com/ci/mirrorProblem.htmlhttp://www.mathpages.com/home/kmath441.htmhttp://www.mathpages.com/home/kmath142.htmAs for how to summarise what these links are saying (in a way that your students would understand, say) ... well, I'll leave that for you to do as your homework.[}:)]Paul.

quote:Originally posted by DoctorBeaverI think the problem lies in how we've all had it explained to us at school - you know, the angle of relection thing.
quote:What I wanted to know is why isn't the image we see the size of where those lines touch the mirror? In other words, if the light from our feet hits the mirror halfway between our feet & our eyes, why doesn't our reflection look only half as tall as we really are?
quote:2. Place the letter 'p' in front of you, then hold a mirror to your side (so that it's upright and at right angles to both you and the letter). Now look at the image of the letter in the mirror. You'll find it's no longer a 'p', instead it's a 'q'.This works whether the mirror is on your left or on your right.
