A string of length 0.67 m and mass 2.0 g is held at both ends under tension. The string produces a 700 Hz tone when it vibrates in the fourth harmonic. During this event, what is the
wavelength of the standing wave in the string?

.34
.55
.61
.45
.49

The value is  

Explanation:

From the question we are told that

     The length of the string is  

      The mass is  

      The frequency produced at  fourth harmonic vibration(i.e n =4 )  is  

  Generally the wavelength of the string is  mathematically represented as

=>            

=>
