i made a program on my calculator for energy of a photon, because typing in 3 *10^8 and 6.63*10^-34 every second didn't seem very fun. but idk if its exactly right...so i want to check it here. what would the energy of a photon in joules be if it had a wavelength of 6*10^-7. i get 3.315 ^-19. doesnt seem right to me...seems to small.

"Joule" is a pretty big unit of energy for a photon, which is why the electron-Volt is used. To check:
E = hc / λ = ( 6.64 x 10^-34 J-s ) ( 3.00 x 10^8 m / s ) / ( 6 x 10-7 m ) = 3.32 x 10^-19 J, which confirms your answer.

chum..what u have reported are actually not wavelenghts..yet are artwork applications of the three cones..multiply each of them by utilising a million.6*10^-19 J and u gets the photon energies of the three cones in joules....
