In a photo electric experiment, the photo sensitive target metal surface is illuminated by red light and the saturation current is found to be i. If in the above experiment, red light is replaced by violet, light having same intensity ten saturation current is found to be $$i1$$, then

In a photo electric experiment, the photo sensitive target metal surface is illuminated by red light and the saturation current is found to be i. If in the above experiment, red light is replaced by violet, light having same intensity ten saturation current is found to be $$i1$$, then

Infinity Learn · Accepted Answer

If n be the number of photons passing through unit area of the incident light beam and I be the intensity of incident light, then $$I=nh$$ν where hν is the intensity of individual photon. Now ‘hν’ for violet > ‘hν’ for red ∴ ‘n’ for violet < ‘n’ for red Since saturated photo current x n, we can conclude $$i1$$

In a photo electric experiment, the photo sensitive target metal surface is illuminated by red light and the saturation current is found to be i. If in the above experiment, red light is replaced by violet, light having same intensity ten saturation current is found to be $i^{1}$ , then
