Question

a sound wave travels at a speed of 330 M per second if its wavelength is 1.5 CM then calculate the frequency of sound wave

Answer 1

Formula :

Velocity = wavelength × frequency .

Given :

Wavelength = 1.5 cm

                    = 0.015 m

Velocity = 330 m/s

Calculation :

330 m/s = f × 0.015 m

= > f = 330 m/s / ( 0.015 m )

= > f = 330 m/s / ( 15 / 1000 ) m

= > f = 22 × 1000 Hz

= > f = 22,000 Hz

ANSWER:

The frequency is 22,000 Hz
