derive the formula for convex mirror.
Answers
The derivation of mirror formula is given below. The diagram given below will help learners to understand the mirror formula derivation more effectively.

From the figure given above, it is obvious that the object AB is placed at a distance of U from P which is the pole of the mirror. From the diagram we can also say that the image A1B1 is formed at V from the mirror.
Now from the above diagram, it is clear that according to the law of vertically opposite angles the opposite angles are equal. So we can write:
