A steel cable with total length 48 m and mass 140 kg is connected to two poles. The tension in the cable is 2,222 N, and the wind makes the cable vibrate with a frequency of 2 Hz. Calculate the wavelength of the resulting wave on the cable.

Wavelength = 0.143 m

Explanation:

Given that,

The length of a cable, l = 48 m

Mas of the object, m = 140 jg

The tension in the cable, T = 2222 N

The frequency of the cable, f = 2 Hz

We need to find the wavelength of the resulting wave on the cable.The speed of a wave in the string is given by :

Put all the values,

Let the wavelength is . We know that,

So, the wavelength of the resulting wave is 0.143 m.
