Number of photons and intensity

Postby Simrina Desar Dis 1H » Sat Dec 09, 2017 9:04 pm

Does increasing the number of photons of light shone on a metal result in an increase in the intensity/amplitude of light?

No, increasing the number of photons will not remove an electron from the metal. The only way to remove it is to increase the energy, by increasing the frequency. E=frequency x Plank's Constant.

yes, increasing the number of photons does increase the intensity of the light, but in the photoelectric effect since we are talking about light as particles (photons), increasing intensity has no effect on removing an electron from the metal surface. to do that you must increase the frequency at which the particles are hitting the metal surface.
