Question

When you blow a whistle, the vibrations of particles in air produce sound . Why ?​

Answer 1

Answer:

Blowing a whistle forces air through the mouthpiece's rectangular tube until it runs into a slotted edge. The slot divides the air in two, creating oscillating sound waves that then tumble around the resonate chamber, or barrel. As the compressed air escapes from the hole on the other end, it creates an audible pitch.

Answer 2

When you blow into a whistle air enters the whistle at one end. As the air reaches the other, closed end, all the air molecules “pile up” on top of each other and cause a high-pressure region. The vibrating air escapes out the little hole at the top making noise.
