Why do low frequency waves travel further than high frequency waves?
Answer > have read that lower frequency electrromagnetic waves > travel further that high frequency waves The distance an EM wave travels depends not only on its frequency, but on the medium it is traveling through. When you do the calculations on radio waves in the atmosphere, low frequency waves are indeed less attenuated than high frequency radio waves. > high frequency waves carry more energy > (stronger electric/magnetic fields An individual photon of a higher frequency wave does indeed carry more energy. But there are two more things to consider: 1) the number of photons created at the source. 2) the absorption and scattering rate for photons. Thus, a high-power, lower frequency wave will have stronger EM fields than a low-power, higher frequency wave. And in some cases, a higher frequency wave is more absorbed or scattered than a lower frequency one. For example, UV light from the sun is higher frequency than visible, but is almost complete absorbed by our atmosphere. Am not fam
