The teacher facilitates classroom learning. 1  The teacher's daily, weekly, monthly, and yearly facilitation plans focus on setting content learning in a conceptual framework. 2  She accepts that teaching is also a learning process. 3  He asks questions, encouraging divergent thinking that leads to more questions.
Noun. 1. intensity-the amount of energy transmitted (as by acoustic or electromagnetic radiation); he adjusted the intensity of the sound; they measured the station's signal strength. intensity level, strength. radio brightness-the strength of a radio wave picked up by a radio telescope.

This means, that if you have two beams with equal intensities, the area is the same and the power has to be the same as well.You are probably confused by the relation between frequency and energy of a photon, $E_\nu = h\nu$. But this says just, what the energy of a single photon is.s @daaxix says, you have used intensity to mean irradiance. Irradiance is the amount of power the wave has delivered per unit area and hence, $W/m^2$. Both are quite similar in their definitions. Or in other words, the amplitude of the wave determines the irradiance.
