Question

the frequency of a source is 80 hz find the number of times it vibrates in a minute

Answer 1

One minute has 60 seconds and frequency is for one second

Therefore

60x80=4800

Answer 2

☆$\red {HELLO\:DEAR}$☆

Frequency is defined as the number of oscillations per second. It is given by the relation:

Frequency = Number of Oscillations / Total Time

Number of oscillations = Frequency × Total time

Given, Frequency of sound = 80 Hz

Total time = 1 min = 60 s

Number of oscillations/Vibrations = 80 × 60 = 4800

Hence, the source vibrates 4800 times in a minute, producing a frequency of 80 Hz.
