electromagnetic energy is quantized (it only comes in discrete units related to the wave function)....(adsbygoogle = window.adsbygoogle || []).push({});

my exam krackers book says: "if we transfer energy from one point to another via an electromagnetic wave, and we wish to increase the amount of energy that we are transferring without changing the frequency, we can only change the energy in discrete increments given by:

[itex]\Delta[/itex]E = hf

my question is:

Based on the equation, how can you increase the amount of energy that you are transferring without changing f (since h is a constant)?

does increasing the amount of energy this way mean using more photons?
