To Calculate: The ratio of intensities of two sound waves.
Answer to Problem 19P
The ratio of the intensities of two sound waves is 4.
Explanation of Solution
Given:
Both the sound waves having equal displacement and amplitudes.
Formula used:
The intensity is given as,
Here,
Calculation:
In the given formula, all quantities are constant except for the frequency.
Therefore, the ratio of intensities of two sound waves is equal to the ratio of square of their frequencies,
Conclusion:
The ratio of intensities is 4.
