Frequency of the wave is 2 per second
Explanation:
- Frequency is the number of times waves pass at a particular point of time. Here, given time period = 3 s and number of waves that pass in 3 seconds = 6. Find the frequency of the wave per second.
- Frequency is given by the formula
f = 1/T, where f is the frequency and T is the time period
- For 3 seconds, frequency is 6
3 seconds ⇒ 6 waves
⇒ 1 second = 6/3 = 2 waves per second
