In an optics experiment, with the position of the object fixed, a student varies the postion 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 th elens, is plotted using the same scale for the two axes. A straight line passing through the origin and making an angle `45^(@)` with the x-axis meets the experimental curve at P. The coordinated of P will be:

A

(2 f, 2f)

B

`((f)/(2), (f)/(2))`

C

(f, f)

D

(4 f, 4 f)

Text Solution

Verified by Experts

The correct Answer is:
A
At centre of curvature object and image are coinciding i.e. (2 f . 2f)
