- Visit these web sites for more
information:
- If you have a makeup or shaving mirror, you
can use it to form a real image (I assume you've seen the virtual
image- when you look into it!) To see a real image, stand in a
room, away from the windows. If you can lower the shades that
helps. (Too much light in the room overpowers the image you are
trying to see.) Leave one window shade open about 12 inches, and
face the concave side of the mirror toward that window (this is
your object). Hold a piece of paper between the mirror and window,
but lowered enough so light can still reach part of the mirror.
(You may need to tip the mirror down toward the paper.) Move the
paper back and forth until the image is formed. Is it upright or
inverted?
