Chapter 22, Problem 9Q

To determine

Whether the radio wave and sound wave can have same frequency.

Answer to Problem 9Q

Solution:

Yes they have same frequency, the radio waves would have extremely long wavelengths if the same frequency as sound

The radio wave frequency ranges from 300 GHz to 3000 Hz.
The sound wave frequency ranges from 20,000 Hz to 20 Hz.
Thus, Radio wave and sound wave can have same frequency ranging from 3000 Hz to 20,000 Hz but the characteristic of these two waves are entirely different.
The Major difference between radio wave and sound wave doesn’t require any medium for propagation while sound waves require.

Explanation of Solution

Conclusion:

The difference between radio wave and sound wave doesn’t require any medium for propagation while sound waves require.
