Description

A lighted object and a concave mirror set up as photographed produce a real image, which is cast onto a screen. Two mirrors are available: 100 cm focal length and 30 cm focal length. The optical table is positioned three to four meters from the screen, and the mirrors can be adjusted slightly to obtain a good focus.
