Photoelectric current: why does it decrease?

Click For Summary
The discussion centers on the relationship between photoelectric current, intensity, and wavelength. It is noted that while intensity is kept constant, decreasing the wavelength leads to a decrease in photoelectric current, which seems counterintuitive since more photons should release more electrons. The explanation involves the energy required for electrons deeper within the metal to escape; shorter wavelengths provide higher energy photons, allowing deeper electrons to be released. However, if the intensity remains constant while decreasing the wavelength, fewer photons may reach the surface, resulting in a lower current. Ultimately, the interplay between photon energy and the number of photons affects the overall photoelectric current.

In my book it is stated.When you keep the intensity constant and decrease the wavelength the photoelectric current decreases but I can't understand why?

I thought it would stay the same since photoelectric current depends on the intensity of photons as more number oh photons means more e- released
 
Physics news on Phys.org
Are you talking about stopping potentials experiments? As in when EM radiation falls on a plate A and a potential difference is applied across plates A and B such that B is more negative?
 
Should that not be the other way around?

The electrons are not just being released from the surface. The ones further inside need to have more energy to escape the surface. If the wavelength of light is shorter electrons from further inside will make it out.
 
The experiment is you supply light (photons) on a metal surface to release e-
then they said 240 nm wavelength of radiation gives Max Photoelectric current.After that they said Intensity is constant and wavelength is reduced causing the current to decrease but I simply can't understand why
 

Thread 'Two equivalent statements of time reversal symmetric Hamiltonian'

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
