Intensity vs energy of light

Nettet14. aug. 2024 · There are many ways of defining the intensity of light, but if you are just measuring the energy per unit time per unit area then yes increasing the frequency while keeping the number of photons constant will increase the intensity. Nettet12. sep. 2024 · The light intensity corresponds to the number of photons arriving at the metal surface per unit time. Even at very low light intensities, the photoelectric effect …
