Question

vibrating wire produce 600 vibration in 1 minute find its frequency and time period of vibration

Answer 1

600 oscillations in 60 seconds

Frequency = No.of oscillations / Time taken
= 600/60 = 10 Hertz

Now,
Time period = 1/Frequency = 1/10 seconds = 0.1 seconds

Answer 2

Frequency is 10Hz

Time period is reciprocal of frequency i.e., 1/10s or 0.1s
