I just tried setting up a proportion equation to see if that would help. (size of the mirror/how much of my body I can see.) This is random but can't I say that I could just stand on a mirror and see my whole body that way?!?:

for this question I said that, an object need to be present for an image to exsit since an image is the reflection of an object in a mirror or any other shiney surface (its something visual and not physical)

[SIZE="4"]Does a person have to be present for an image to exsit? (use operational definition of an image)[FONT="Comic Sans MS"]

I see. We just covered optics in class, so I am trying to demonstrate my answer with ray diagrams and show with arrows the light rays from the image (me) to the mirror and back to my eye. Not sure what the distance and the angles are though.

This is a bonus question on a test and I am not sure if there is a definite answer for it or not.

I haven't actually taken out a mirror to experiment with, if that's what you are asking.

Shortest mirror that will work... [FONT="Century Gothic"]1. How long does a "full length" mirror have to be to allow you to see your whole body? What is the shortest mirror that will work? How should a mirror be positioned? :rolleyes:
