on increasing intensity number of photons increased but the energy on each photon is same then suppose intially no photons is 100 and energy is 500 on increasing intensity , no of photons increased to 200 and energy to 1000 but energy of each photon is 5 which remain same but the total energy increased by 500 , but we also know that energy is independent of intensity so , how energy increased on increasing intensity ,,,, i m confuse
