Question

A wave is traveling through a string and six waves pass a point in three seconds what is the frequency of the wave

Answer 1

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
