Intensity of light

[Jordan Kaplan 2E]

Increasing the intensity of light is just adding photons but how does that affect overall energy? Does the energy overall increase but the energy per photon remains the same?

[Nathan Morgan 2C]

Yes, you are correct! Increasing the number of photons does not affect the amount of energy per photon, it only increases the intensity. The only way to affect the amount of energy per photon is to increase its speed or force.

[Arjun_Anumula_3E]

That's right, increasing the intensity simply increases the quantity of photons in a given beam of light, and it doesn't change the Energy of any single photon.

[Raizel Ferrer 1H]

You're correct! Increasing intensity of light is proportional to increasing overall energy! Energy shouldn't change per photon.

[Irene Kim 3E]

This was the overall foundation of the photoelectric effect; previous experiments had indicated that particles have wave-like properties (in which case energy would increase with intensity), whereas the photoelectric effect illustrated that particles have particle-like properties as well.

yes, increasing the intensity of light just increases the amount of photons, not the energy per photon
