Question

calculate the frequency of sound wave of speed 340m/s and wavelength 0.5m​

Answer 1

Answer:

$c = f \times l$

Frequency, f =c/l

$f = \frac{340}{0.5} = 680 \: hz$

Answer 2

Answer:

The frequency of the sound wave is 680 Hz.

Explanation:

The speed of the sound wave, v = 340 m/s

The wavelength of the sound wave, λ = 0.5 m

The frequency, f of a wave can be calculated using the formula,

Speed = Wavelength × Frequency

        v = λ × f

∴ Frequency, f = v / λ

                         = 340 / 0.5

                         = 680 Hz
