Question
The wavelength of the sound wave shown below is ____ mm.
- 2 mm
- 1.8 mm
- 2.4 mm
- None of them
Hint:
The wavelength of the given sound wave is 2.4 mm.
The correct answer is: 2.4 mm
- Wavelength is the distance between any two corresponding points of adjacent waves.
- The given graphical representation shows the distance between rarefaction points.
- The distance is 2.4 mm, so the wavelength of the sound wave given in the representation is 2.4 mm.
