Energy vs Intensity

[Emily 1E]

What's the difference between the energy and the intensity of photons/light?

[Jack Dias]

As far as I know they are interchangeable, or at least intensity is used to describe how energetic a particle is. Remember that a shorter wavelength and higher frequency makes a particle more energetic and more intense.

However, I think you have to be careful because "intensity" of light (or bright vs faint light) does not affect anything during electron emission, whereas wavelength and frequency will affect this.

[Jose Hernandez 1D]

Energy is usually used to describe the overall energy of a wave while intensity is usually used to describe the power per square meter.

I'm pretty sure that energy level refers to the actual amplitude of the waves whereas the intensity would be the actual amount of energy waves.
