Intensity's Impact on the Photoelectric Effect

Postby Chu 3J » Sun Oct 04, 2015 11:26 pm

In the Chemical Principles book, it mentions that electrons are ejected regardless of the intensity, assuming that the radiation is within the threshold value. Would electrons still be ejected if the intensity was zero or negligible?

Intensity describes the number of photons. If intensity were 0 then there would be 0 photons and nothing would happen.

However, if intensity is very low but the frequency is past the threshold, then electrons can be ejected.
