The-frequency-of-a-drum-note-is-20-Hz-what-does-this-tell-you-about-the-drum-skin-movement

Answer 1

Given:

The frequency of a drum note is 20 Hertz.

To find:

Characteristic movement of the drum skin.

Solution:

The term frequency is defined as the number of oscillations completed by an vibrating particle in one second.

While making of a sound , a drum makes Periodic Oscillatory Motion.

Since the drum makes a note of 20 Hz , the skin of the drum vibrates (or oscillates) at a rate of 20 times per second.

The characteristic movement of the drum skin is

• Periodic

• Oscillatory

• At a rate of 20 times per second.
