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 :
A
$$\left( {{f \over 2},{f \over 2}} \right)$$
B
$$\left( {f,f} \right)$$
C
$$\left( {4f,4f} \right)$$
D
$$\left( {2f,2f} \right)$$
