The given graph shows the displacement versus time relation for a disturbance travelling with velocity of 320 m/s. calculate the frequency and wavelength of the disturbance. time(1 millisecond =1ms=10 raised to -3 seconds

frequency is 1/4 and wavelength 1280 m, whiche is 1.28 *

Explanation:

frequency is where t is the period, we can tell that the period happens once every 4 seconds. This means that the cycle repeats itself once every 4 seconds. Substituting into the formula we get 1/4.

Now the equation of the wavelength is , where v is given as 320 and t we found as 1/4. This means that we times it by 4 to get the answer.

Hope this helps.
