Answer 1

In order to determine focal length of a concave mirror by obtaining the image of distant object on screen, you need to measure the distance between object and screen.

Answer 2

To determine focal length of a concave mirror by obtaining the image of distant object on screen, you need to measure the distance between the screen and the lens.

Explanation:

• If we want to determine focal length of a concave mirror by obtaining the image of distant object on screen, we need to measure the distance between the lens and screen.
• The most precise way to calculate a lens' focal length (especially a short focal lens) is to use a mirror for the target with a flat frame or sillouette in it.
• Then shift both the lens and the frame so the picture is the same width from the lens (also the same size as the target) as the lens is from the subject.
