In an optics experiment, with the position of the object fixed, a student varies the position of a convex lens and for each position, the screen is adjusted to get a clear image of the object. A graph between the object distance

u

and the image distance

v,

from the lens, is plotted using the same scale for the two axes. A straight line passing through the origin and making an angle of

{45^ \circ }

with the

x

-axis meets the experimental curve at

P.

The coordinates of

P

will be :
