JEE MAIN - Physics (2008 - No. 4)
A student measures the focal length of a convex lens by putting an object pin at a distance $$'u'$$ from the lens and measuring the distance $$'v'$$ of the image pin. The graph between $$'u'$$ and $$'v'$$ plotted by the student should look like
Paskaidrojums
This graph obeys the lens equation
$${1 \over v} - {1 \over u} = {1 \over f}$$
where $$f$$ is a positive constant for a given convex lens.
$${1 \over v} - {1 \over u} = {1 \over f}$$
where $$f$$ is a positive constant for a given convex lens.
