a 1-kW raido transmitter operates at 880kHz. How many photons per second does it emit?(adsbygoogle = window.adsbygoogle || []).push({});

Power=work/time

Power=change in KE/time

f=1/T

T=1/880kHz

so 1 kw=change in KE/1.136x10^-6

change in KE=.00136 J

i don't know if i am doing this right. please point me in the right direction.
