What cause frequency change of the acoustic signal (3 kHz to 10 kHz)?

1. What causes frequency to change in sound?
2. What is frequency of sound Class 10?
3. How does change in frequency affect sound?

What causes frequency to change in sound?

As you see, sound frequency is determined by the way in which sound waves oscillate whilst travelling to our ears, meaning that they alternate between compressing and stretching the medium, which in most cases is air. In the same medium, all sound waves travel at the same speed.

What is frequency of sound Class 10?

Ans: The frequency is the number of waves that pass with a fixed point at a specific time. It can also be defined as the number of vibrations during one unit of time.

How does change in frequency affect sound?

The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
