How is the distance between the object and the mirror calculated? Is the difference between the object and image distance or their sum? Please answer.

Remember to wrap math in $$...$$ or $...$ to ensure proper formatting.
2 \times 3 $$2 \times 3$$

Sort by:

there is mirror formula for this::::1/f=1/v+1/u . where f=focal length v= image distance and u= object distance. Remember sign conventions that direction along incidence ray is always taken to be positive rest all others negative.Ask if you have any doubts....
