Question

The frequency of the 15.ocm string is how many times higher than the frequency of the 30.0cm string

Answer 1

Answer:

2 times.

Explanation:

We know that f = V / λ  ................. (1)

            λ(a)=15 cm

            λ(b)=30 cm

              Va=Vb

Now by using the above formula;

      f_{a} = Va/15 = Va= 15*f_{a}

       f_{b} = Vb/30 = Vb = 30*f_{b}

         As,             Va = Vb

 15*f_{a} =  30*f_{b}

f_{a}  / f_{b} = 30/15

                                  = 2 times
