Whether the bright violet light more electrons than the dim light of the same frequency.
Explanation of Solution
Introduction:
The ejection of the electron from the surface depends on the energy of the incident photon. If the energy of the photon is enough for the ejection then the electron ejects from the surface.
The bright light carries more energy per photon than the energy per photon of the dim light of the same frequency. The energy per photon for bright light is more, so more electrons from the surface ejects. The energy per photon of the dim light of same frequency is very less. So, less electrons does not eject from the surface.
Conclusion:
The bright violet ejects more electrons than the dim light of the same frequency because the energy per photon is more for the violet light than the energy per photon of the dim light of the same frequency.
