Amplitude frequency and energy relation of sound wave
Answers
The amplitude of a wave is how the wave is measured from the rest position or midline to the top of a crest or bottom of a trough, measured in meters. A wave with a large amplitude will be particularly tall, and a wave with a small aptitude will be particularly short.
It turns out that the amplitude tells you how much energy is in the wave. A high amplitude wave is a high-energy wave, and a low-amplitude wave is a low-energy wave. In the case of sound waves, a high amplitude sound will be loud, and a low amplitude sound will be quiet. Or with light waves, a high amplitude beam of light will be bright, and a low amplitude beam of light will be dim.
But amplitude isn't the only factor that affects the energy of a wave. The other factor is frequency. Frequency is the number of ways that pass by each second, measured in hertz. So a wave of a particular amplitude will transmit more energy per second if it has a higher frequency, simply because more waves are passing by in a given period of time.
In fact, in the case of electromagnetic waves like visible light, radio waves, microwaves, infrared, ultraviolet, x-rays, and gamma rays, the frequency and amplitude collectively tell you how much energy is stored inside the wave. For example, light is a wave, but it also contains particles called photons. And each of those photons contains an amount of energy that is proportional to the frequency. So high-frequency light has photons with high energies and appears blue in color.
Thus amplitude and frequency are the two factors that affect the energy transferred by a wave: the height of the wave, and the number of waves passed by each second.
more the amplitude more loud is the sound
and less the amplitude quiet is the sound
more the frequency shriller is the sound
less the frequency flat is the sound
