Question

A string of length 0.67 m and mass 2.0 g is held at both ends under tension. The string

Answer 1

Answer:

The value is $\lambda = 0.335 \ m$  

Explanation:

From the question we are told that

     The length of the string is  $l = 0.67 \ m$

      The mass is  $m = 2.0 \ g = 0.002 \ kg$

      The frequency produced at  fourth harmonic vibration(i.e n =4 )  is  $f = 700 \ Hz$

  Generally the wavelength of the string is  mathematically represented as

            $\lambda = \frac{ 2L }{n }$

=>          $\lambda = \frac{ 2 * 0.67 }{ 4 }$  

=>          $\lambda = 0.335 \ m$
