प्रश्न
A longitudinal wave travels at a speed of 0.3 m s-1 and the frequency of wave is 20 Hz. Find the separation between two consecutive compressions.

उत्तर
Wave velocity = 0.3 m/s
Frequency = 20 Hz
Separation between two consecutive compressions is the wavelength of a wave.
We know that,
Wave velocity = Frequency × Wavelength
Or, wavelength = `"Wave velocity"/"frequency"`
Or, λ = `0.3/20`
= 1.5 × 10-2 m
