[VenomP]

An FM radio station transmits at a frequency of 102.8 MHz (how many Hz in a MHz btw?). What is the energy, in joules, of each photon emitted by the transmitter?

E=hf
= 102.8*10⁶*h

The answer is 6.812 x 10^2 apparently. :S

An FM radio station transmits at a frequency of 102.8 MHz (how many Hz in a MHz btw?). What is the energy, in joules, of each photon emitted by the transmitter?

E = (6.626x10^-34)*(102.8x10^6) [Mega = 10^6]

E = 6.812x10^-26J

that's it

answer is wrong

We wouldnt live to long if each photon of a radio wave had 680J of energy as the answer suggests

U have UAI Aim of 98 and u dont know what M means!?!?!?!?!

AYE AYE AYE!!!
