<h2>The frequency of driver is 700 Hz</h2>
Explanation:
The frequency of wave in a string is given by the relation
n =
here n is the frequency
p is the number of antinodes and l is the length of string .
T is the tension in string and m is the mass per unit length
Thus 420 = I
Now if there is 5 antinodes , the value of p = 5
Thus n = II
Dividing II by I , we have
n/420 = 5/3
or n = 5/3 x 420 = 700 Hz
