If a note was "fretted", by reducing the length of the string to 0.25 m, then the lowest frequency note this string could play is?
I am not certain of the term fretted. The lowest frequency will be the longest wavelength, so that normally means the length of the string will be 1/2 wavelength at the lowest frequency.
I do not understand how to solve the problem still.
