If it takes approximately 1erg of energy for a fly to lift off from a table top how many flies could get air ball by Avogadro's no. Of photon of yellow sodium light of wave length 5800A

the energy released in this process is aproximately 12.9*[10 power 23] ev which is equal to 2066807768850erg aproximately thus that mant flies can be air brone with the gven energy

also the energy is calculated by the formula E={\frac  {hc}{\lambda }} from the chapter photo electric effect where h is plancks constant, c is speed of light and lamda is the wavelength of incident photons
