Hey all, is there a formula that can calculate the energy losy by a photon travelling through air at 1 atm per meter given frequency? Any help apreciated.
Yea, but wouldnt it be absorbed and reemitted at lower energy on average a certain number of times or would that be too capricious to be used?However, a photon may be absorbed and cease to exist.
Yea, microwave/radioDo you have a particular frequency range in mind? (radio, visible, X-ray, gamma-ray, ...?)
So you are interested in radio wave propagation. There is loads of information about that and I recommend that you google appropriately to get some background and to find out the actual questions that need answering for your problem.Yea, microwave/radio
as you have been told ... forget about individual atoms ... that's irrelevantHey all, is there a formula that can calculate the energy losy by a photon travelling through air at 1 atm per meter given frequency? Any help apreciated.
OK that is relatively straightforward and is used all the time for us doing pathloss calculations between radio transmit and receive sites............................ Yea, microwave/radio
the 2 popular ones are Radio Mobile and UKW ToolsYou should try to find stuff on 'Link Budgets". That takes everything into account; transmit power, feeder loss, antenna gain, path loss, spreading loss, etc etc and can give you a Carrier to noise ratio for the demodulated signal. Just what a chap needs. Path loss on its own is not actually a lot of use for designing a practical system.
