answer; //the above statement is (false);

where is the diagram?

if you insert the diagram ill be able to you

your spelling is a little off : ]

energy per photon is e = h*c / λ  

e = 6.63*10^-34 * 3*10^8 / 6*10^-7 j = 3.315*10^-19 j  

nr. of photons = 10j / 3.315*10 = ^-19 j per photon = 3.02*10^19 photons
