(A)   cepat rambat bunyi

\begin{equation*}
\begin{split}
v &= \sqrt{\frac{F}{\mu}}\\\\
v &= \sqrt{\frac{F}{\dfrac {m}{L}}}\\\\
v &= \sqrt{F \:.\: \frac LM}\\\\
v & = \sqrt{100 \:.\: \frac {0,25}{0,01}} \\\\
v &= \sqrt{2500}\\\\
v &= 50 \text{ m/s}
\end{split}
\end{equation*}

(B)   frekuensi nada dasar

\begin{equation*}
\begin{split}
f_o &= \frac {v}{2L} \\\\
f_o &= \frac {50}{2 \:.\: 0,25} \\\\
f_o &= 100 \text{ Hz}
\end{split}
\end{equation*}

(C)   frekuensi nada atas ketiga

Perbandingan frekuensi = \(f_o : f_1 : f_2 : f_3 = 1 : 2 : 3 : 4\)

Frekuensi nada atas ketiga = 4 kali frekuensi nada dasar = 400 Hz
