Question

Write the precautions to be taken in the experiment that the image formed when an object is kept at distinct locations on the principal axis before a concave mirror

Answer 1

Concave mirrors form an inverted an real image, thereby decreasing the size as moved away.

The precautions to be taken care of are -

• Concave mirror's polished side and the distinct object must be facing each other.
• The distant object should be positioned in a completely illuminated region to get a distinct image.
• The concave mirror and the screen must be in a straight line, or they can be placed in a position parallel and inside the measuring scale range.
