Question

the frequency of sound wave is 200 hz. how many times does it vibrates in a minute

Answer 1

Answer:

vibration in 1 minute = 3.3

Explanation:

v=200

time = 60 seconds

now,

vibration in one minute = 200÷60 = 3.3

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 = 200 Hz

Total time = 1 min = 60 s

Number of oscillations/Vibrations = 200 × 60 = 6000

Hence, the source vibrates 12000 times in a minute, producing a frequency of 200 Hz.
