Question

what is meant by amplitude, frequency and time period of sound.
​

Answer 1

1. the greatest distance that a wave, especially a sound or radio wave, moves up and down.

2. Frequency is the number of occurrences of a repeating event per unit of time

3. A time period (denoted by 'T' ) is the time taken for one complete cycle of vibration to pass a given point. As the frequency of a wave increases, the time period of the wave decreases. The unit for time period is 'seconds'.

Answer 2

Answer:

Physical value:

Cycle duration

Frequency

Wavelength

Wave speed

symbol :

T = 1 / f

f = 1 / T

λ

c

:formula

T = λ / c

f = c / λ

λ = c / f

c = λ × f
