If the speed of sound in a medium is 340 m/s and a sound wave has a frequency of 680 Hz, what is its wavelength?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 0.5 m.
The relationship between the speed of sound (v), frequency (f), and wavelength (λ) is given by the formula, v = f x λ.
To find the wavelength, we rearrange the formula as λ = v / f. Substituting the given values: λ= 340 m/s / 680 Hz = 0.5 meters.
This indicates that the distance between consecutive compressions or rarefactions in this sound wave is half a meter.
