Question

a sound wave travels at a speed of 339 metre per second if its wavelength is 1.5 CM calculate the frequency of the wave

Answer 1

v = 339 m/s
wavelength = 1.5 cm = 0.015 m
v = wavelength*frequency
v/wavelength= frequency
339/0.015=frequency
22600 Hz = frequency

Answer 2

Here v=339m/s

Wavelength=1.5cm=0.015m

Frequency=?

We know,

Speed(v)=wavelength×frequency

or,339=0.015×frequency

or,339÷0.015=frequency

or,339×1000÷15=frequency

or,frequency=22600Hz
