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.
Intensity is power per unit area. Power is energy per time. For a photon, the energy is $h\nu$. So, the intensity will be $$I=Nh\nu / A$$ if $N$ is the monochromatic photon emission rate (photons per second), $\nu$ is the frequency of the photons, and $A$ is the area these photons are hitting.
