Question
A sound wave traveling at a speed of 500 m/s has a frequency of 50 Hz. Its wavelength is ___ m.
Hint:
A sound wave traveling at a speed of 500 m/s has a frequency of 50 Hz. Its wavelength is 10 m.
The correct answer is: 10
- The wavelength is equal to the difference between the speed and frequency of the sound wave.
- If the speed and frequency for a sound wave are 500 m/s and 50 Hz respectively, the wavelength can be derived by dividing them.
- Wavelength = 500/50 which is 10 m.
