Question

a pendulum oscillates 40 times in 4 seconds. find its time period and frequency .​

Answer 1

Answer:

Frequency

$= \frac{40}{4} = 10 \: \: times$

Time Period

$= \frac{40}{4} = 10 \: \: oscillations \: \: per \: second$

Answer 2

Answer:

The number of oscillations per second of the vibrating body is known as the frequency of oscillation.

Frequency = Total number of oscillations

Total time taken

= 50/5

= 10 Hz

Time period is the time taken to complete one oscillation. It is also the inverse of frequency.

Time period = 1/ Oscillating frequency

= 1/10

= 0.1 s

∴ frequency = 10 Hz

Time period = 0.1 s
