Figure given shows a sinusoidal wave on ...

Figure given shows a sinusoidal wave on a string. If the frequency of the wave is 150 Hz, what is the velocity and wavelength of the given wave?

A

2.34 W

B

3.84 W

C

4.80 W

D

5.78W

Text Solution

Verified by Experts

The correct Answer is:
B
Mass per unit lenght = 0.2g/m `=0.2xx10^(-3)` kg/m
Amplitude `(A) = 0.06 m, 5/2 lamda= 20` cm
`lamda = 40/5 = 8 cm=8xx10^(-2)m`
Velocity (V) `= lamdav = 150xx8xx10^(-2) = 12` m/s
Power `(P) = 2pi^2 v^2 A^2 muV`
`= 2xx (3.14)^2 xx (150)^2 xx(0.06)^2 xx(0.2xx10^(-3))xx12 = 3.84` Watt.
