Question

Figure shows a plot of three curves a, b, c showing the variation of photocurrent v/s collector plate potential for three different intensities I1, I2, I3 having frequencies v1, v2,v3 (nu) respectively incident on a photosensitive surface.
Point out the curves for which the incident radiations have same frequency but different intensities.

$\bold{Don't try to Google it.}$​

Answer 1

$\Huge{\boxed{\mathbb{\red{ANSWERS}}}}$

For the curves a and b, the stopping potential is same. Hence for curves a and b, the frequency of incident radiation is same (v1 = v2) but intensities I1 and I2 are different.

will u please tell me it is ICSE board or CBSE___??,,,,
