the displacement veres time relation for...

the displacement veres time relation for a disturbance travelling with a velocity of `1500 m//s`.
Calcuate the :
(i) time period
(ii) frequency
(iii) wavelength of the disturbance.
.

Text Solution

Verified by Experts

(i) Time period `(T) = 2 s` (time interval between the centres of two crests or two troughs)
(ii) Frequency, `v = (1)/(T) = (1)/(2 s) = 0.5 Hz`
(iii) Wavelength, `lamda = (v)/(v) = (1500 m//s)/(0.5 Hz) = 3000 m`.
