Please answer question 43
Q 43 State the precautions that should be taken while doing the
experiment, to determine the focal length of a concave mirror by
obtaining the image of a distant object

Christeena Shaju · Accepted Answer

The distant object should be clearly visible
The image on the wall should be well defined and sharp
(Student must pay special attention to get the sharp image
Obtaining a blurred image will give you an incorrect measurement of
the focal length of a concave mirror)
While measuring the distance, the meter scale should be kept
parallel to the ground
The meter scale must be correctly positioned between the wall
and center of the concave mirror Important note: This
experiment can be performed outside the laboratory by taking the
image on the screen (white paper) or white painted board or outer
wall of the laboratory
