Question

State the sign convention used for studying the formation of image by a spherical mirror

Answer 1

Answer:

Sign Convention for Spherical Mirrors (Concave and Convex Mirrors)

Distances are to be measured from the pole (vertex) of the mirror marked by point V in the figure.

Distances measured along the direction of the incident ray are positive. The distance measured opposite the direction of the incident ray are negative.

Distances measured above the principal axis are positive. Distances measured below the principal axis are negative.

The above convention applies to both concave and convex mirrors .
