Energy Transport and the Amplitude of a Wave. As mentioned earlier, a wave is an energy transport phenomenon that transports energy along a medium without transporting matter. A pulse or a wave is introduced into a slinky when a person holds the first coil and gives it a back-and-forth motion. This creates a disturbance within the medium; this ...

Let's take a look at the method of adjusting the amplitude of the electromagnetic vibration feeder together: (1) Adjusting the applied voltage. Because the amplitude is proportional to the square of the voltage, the feeding speed of a vibrating feeder is highly sensitive to changes in voltage. In feeders that require a very stable …

Due to more vibration, the wavelength increases lead to the increase in the height of amplitude of a wave. When the amplitude increases in a wave, it carries more energy and gains higher intensity; in terms of sound waves, if the intensity is high, then the quality of sound will be loud. To understand the relation between amplitude and a wave.
