planck's postulate




that energy (motion times time) does not occur in a continuous stream


on the contrary, it occurs in discrete, fixed amounts (quanta) and that the number of quanta increases as the length of the wave becomes smaller (approximately doubling and halving)





for 10 metre wavelengths 10 quanta


for 5 metre wavelengths 20 quanta


for 2 metre wavelengths 50 quanta
