A string fixed at both ends first oscillates in its
\( \mathrm{P} \)
fundamental mode than in second harmonic mode.
W
Then match the following.
\begin{tabular}{|l|l|l|l|}
\hline \multicolumn{2}{|c|}{ Column-I } & \multicolumn{2}{c|}{ Column-II } \\
\hline (A) & Frequency & (P) & \begin{tabular}{l}
In second \\
case is more
\end{tabular} \\
\hline (B) & Wavelength & (Q) & \begin{tabular}{l}
In second \\
case is less
\end{tabular} \\
\hline (C) & Energy of string & (R) & \begin{tabular}{l}
In second \\
case is same
\end{tabular} \\
\hline
\end{tabular}
