Well technically I'm what's called a biochemist. Our experiment has nothing to do with solar flux or anything environmental. We are testing a new set of drugs that become activated by direct irradiation by light after cell uptake in drug-resistant bacteria and we are optimizing the parameters of...
Avogadro's is used to define a mol of anything really and even the instrument assures that the number of micromoles of photons is indeed a measure of n*6.022x10^17 photons. That aside, I can't use that measurement only as it measures the flux. I needed power. The instrument measures in...
well avogadros constant is just to account for the fact that the equation you gave me is for only one photon. I simply scaled it using avogadro's number so I could directly input my measured value. I didn't modify it further to account for the micro factor, but I would in the end result.
ok nice, so can I assume that the work being exacted by photon is equal to its energy?
so that would mean W=nhc/λ, and power would be (n*h*c)/(λ*t)...
would it follow that watts/m^2 for my needs is simply [(NsubA*x*h*c)/(λ)] where x is my measured units as stated previously? *NA being...
It doesn't do anything, it is just a representation of a scaling factor (you know this factor as Avogadro's constant). The reason we like using the mole in equations as opposed to just one particle is that it is simply easier. Easier for measurements and easier for calculations. Since it's early...
A mole is a unit that quantifies 6.022 x 10^23 of a particular element, molecule, or particle.
so if you had a mole of dogs, you would have 6.022 x 10^23 dogs, more than enough to cover the surface of the world! A more likely example is if you had a mole of hydrogen atoms; you would then have...
Hello all of you very bright physicists,
The local physics dept. is not answering us thus far and long story short we need a rough estimate of the power of a light source based on wavelength and a measured concentration of photons.
We need a method of converting the photon concentration...
