kindly ans. this.

These instruments have strings fixed at both ends, and vibrations set up on strings fixed is inversely propotion to the length. Also on the tension in the string, and linear mass density.

If we assume tension and linear mass density to be the same, the length is only the parameter.

Smaller length, then we'll have higher frequency.

So length comparison will tell you about the relative frequencies generated on the instruments.
