Question

A wave has a frequency of 5Hz, how long does it take to complete one cycle?

Answer 1

Frequency is defined as number of cycles completed per second.

and, Time period is defined as time taken to complete one cycle,

And, Time period and frequency relation is also given as:

Time period = 1 / frequency

here, f = 5 Hz

or, time period = 1 / 5 = 0.2 s

Therefore, It takes 0.2 second to complete one cycle.

Answer 2

Frequency is defined as number of cycles completed per second.

and, Time period is defined as time taken to complete one cycle,

And, Time period and frequency relation is also

given as:

Time period = 1 / frequency

• here, f = 5 Hz
• or, time period = 1 / 5 = 0.2 s

Therefore, It takes 0.2 second to complete one cycle.
