"WebRadio waves are received by another antenna attached to a radio receiver. When radio waves strike the receiving antenna they push the electrons in the metal back and forth, creating tiny oscillating currents which are detected by the receiver. " - How does amplitude affect radio waves

How does amplitude affect radio waves

Does a wave energy depend on his amplitude or his frequency?

WebThe amplitude is related to the frequency by the relation x=ASin (ω t+φ) where x is a displacement of the wave, ω is an angular frequency, φ is a phase shift in radians and t is a time period of a wave. The angular velocity is the radial velocity and is equal to ω =2π/T=2πf hence the equation above gives the relation between the ... WebRadio waves may be propagated in one or more of five modes, depending upon the medium into which they are launched and through which they pass. These modes are: 1. Free space propagation, where radio waves are not influenced by the earth or its atmosphere. 2. Ground wave propagation, where radio waves follow the surface of the earth.
