     An erg is a certain amount of work. It is a dyn-cent.

 

     It requires a period of time or a region of time.

 

     If that period is one sec, then dividing the erg by that period gives the rate of work — so many ergs par sec — which is the rate at which the mass particle can perform work.

 

     If that period is 1/10 sec then the rate at which the particle can perform work which is a rate of 1/(1/10) = 10 ergs per sec. So the number of ergs per sec times the frequency of occurrence during that time, is

 

     So – Number of ergs per sec (which in this case is one) times the frequency, is the energy-rate at that frequency.

 

     Now suppose the number of dyne-cm per second, is instead of 1 erg per sec should be h dyn-cent (ergs) per second, and this very small energy rate — so much energy (ergs) per second during one period (second) of time times the frequency per second gives the energy rate during ..
