Question

Vibrating object complete 450 oscillation in 15 seconds what is the frequency of vibration of that object?​

Answer 1

Frequency = Number of Oscillation / Time taken

=> f = 450/15

=> f = 30

Answer : 30

Answer 2

Answer:

450 oscillations,

$\frac{450}{15}$

= 30 oscillations on will be completed in one second.

Therefore, The frequency of oscillation of that object is 30 Hz .
