If the frequency of a sound wave is 250 hertz and its wavelength is 1.36 meters, what is the wave's velocity?

340 m/sec

Explanation:

A wave speed is usually defined as the distance that a wave covers in a given amount of time. It is commonly represented in terms of numbers of meters a wave moves per second.

Given that,

Frequency of sound wave, f = 250 Hertz

Wavelength, λ = 1.36 meters

Mathematically,

⇒ Wave velocity (speed) = Frequency × Wavelength

⇒ v = 250 × 1.36

⇒ v = 340 m/sec
