Have a look at the wave of a string: (Image will be uploaded soon) These waves move from left to right at a constant speed. Amplitude is a measure of the size of sound waves. So whatever change occurs in the amplitude, the square of that effect impacts the energy. Your email address will not be published. The main difference between amplitude and magnitude is that amplitude refers to the furthest values that a quantity can take from 0 whereas magnitude refers to the size of a quantity regardless of direction. When watching ocean waves approaching shallower water, this effect is very noticeable. There are primarily two types of waves, which are listed below: Amplitude: The total distance between a waves resting position and the maximum displacement it can span is referred to as its amplitude. In sound, amplitude refers to the magnitude of compression and expansion experienced by the medium the sound wave is travelling through. The crest is observed to cover distance. The relation between the energy of the wave and the amplitude of the wave is given as below: Where letter E denotes the waves energy, and letter A denotes the waves amplitude. So, from all the facts considered above, we can say that increasing the source of energy that transfers in a media changes the amplitude of a wave.
