Asked by Hannah
We have to conduct a lab experiment for a photochemical reaction. We will be using a redand violet film and filter paper labeled 40W and 60W. On each piece of paper we will add 1 drop of NaCl and AgNO3 and then let it sit under a lamp to see what happens. At the end we will obtain a transmittance spectrum from a spectrophotometer which will have the wavelengths from 300-700nm. The question says to calculate the energies for the red and violet films and remember to convert nm to meters.
1nm=1 X 10^-9m
So that I can be prepared to do these calculations I was just wondering how I would go about finding the energy because I am not sure.

E = hc/wavelength.
E is in joules.
h is Planck's consant in J*sec
w = wavelength in m.
