Question

define:
a. amplitude
b. pitch
c. frequency
in eight grade level ​

Answer 1

Answer:

AMPLITUDE-Amplitude of the sound is nothing but the loudness or the amount of maximum displacement of the particles while the sound is produced. When the amplitude of the vibration is large, the sound produced is loud. When the amplitude is small, the sound is feeble.

PITCH:

Pitch denotes the shrillness or flatness of a sound. Sound can be high or low.

A woman’s voice generally has a high pitch than a man’s voice. This is because the frequency of a woman’s voice is higher.

FREQUENCY:

The number of vibrations made by the vibrating body in one second is known as its frequency.

The SI unit of frequency is the hertz (Hz).

Answer 2

a) Amplitude :

Amplitude is an important parameter of waves and is the maximum displacement of points on an wave.
