WebThe amplitude of a sound wave decreases with distance from its source, because the energy of the wave is spread over a larger and larger area. But some of the energy is also absorbed by objects, such as the eardrum in Figure 14.5, and some of the energy is converted to thermal energy in the air. Figure 14.4 shows a graph of gauge pressure … WebThe main difference is that there is a phase difference between the amplitude-time curves of the three parameters as shown in the drawing. For sinusoidal signals, displacement, velocity, and acceleration amplitudes are related mathematically by a function of frequency and time, this is shown graphically in the diagram. WebAug 4, 2024 · Because (in a vacuum) the amplitudes of both perpendicular fields of the electromagnetic wave are proportional, we can say the intensity is proportional to both the electric field and the magnetic field (by different constants).
