Does an AM radio station broadcasting at 750 KHz emit enough energy to ionize a hydrogen atom?
Frequency = 7.5E+5 /s
Ionization E of H atom = 2.18E-18 J
Planck constant h = 6.625E-34 J-s
AM Radio speed = c
Energy AM radio wave = h*frequency
The Attempt at a Solution
This is a topic on my study guide. I am a little confused about the concept of the radio station energy emissions. My calculation for energy of a 750KHz AM radio frequency results in 4.97E-28 J. Is this the amount of energy emitted by the station in 1 second? I am not sure about this, but I am guessing that the station emits 4.97E-28 J continuously, and that an H ion requires 2.18E-18 J continuously in order to remain ionized. So my initial calculations say that there is not enough energy coming from the radio station. Any tips here would be appreciated!
