Two sound waves, $A\,$ and $B$ , are detected by a microphone. The amplitude and frequency of each wave are shown in the table:

\begin{array}{|c|c|c|} \hline & \text{amplitude / mm} & \text{frequency / Hz} \\ \hline \text{A} & 1.5 & 250 \\ \hline \text{B} & 0.8 & 500 \\ \hline \end{array}

How does sound $B\,$ compare with sound $A$ ?

$B$ is louder and has a higher pitch.

$B$ is louder and has a lower pitch.

$B$ is quieter and has a higher pitch.

$B$ is quieter and has a lower pitch.
