week 4 achieve question number 4

Where should i start to solve question 4 on week 4 achieve assessment?

assuming the questions are in the same order, question 4 on the achieve would start by determining the energy of a single photon with a wavelength of 2.53×10^−4 cm using the equation Ephoton=hc/lambda, then you divide the heat absorbed by the energy per photon to get the answer in number of photons.

Hey, if we have the same question 4 for the achieve assignment covering weeks 2 through 4, you first convert wavelength to meters. Once you get that, you can calculate the energy of 1 photon using your wavelength. Now, all you do is divide your total joules of heat by the energy per photon you calculated in the previous step. This should give you your number of photons. Hope this helped.
