Question

A graph is drawn with `(1)/(u)` along x-axis and `(1)/(v)` along the y-axis. If the intercept on the x-axis is `0.5 m^-1`, the focal length of thr lens is (in meter).
A. 2 .00
B. 0. 50
C. 0 .20
D. 1 .00

Answer 1

Correct Answer - A
Intercept =`1/f `
Therefore, `1/("Intercept")=(1)/(0.5)`
=`2 m`.
