Two tuning forks vibrate with the same amplitude, and the frequency of the first is double the frequency of the second. Which fork produces more intense sound in air? The ratio $I_{1} : I_{2}$ is:

Options:

Answer:

Solution:

$I \propto f^{2} A^{2}$ . With equal amplitudes and $f_{1} = 2 f_{2}$ , $I_{1} / I_{2} = 4$ . So the first fork is more intense.
