Question
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 45o with the x-axis meets the experimental curve at P. The coordinates of P will be
Options
A.(2f, 2f)
B.
C.(f, f)
D.(4f, 4f)
Solution
It is possible when object kept at centre of curvature.
u = v
u = 2f, v = 2f.
