Question

calculate the wavelength if the time period of vibrating source producing sound is 0.01 second if the velocity of sound is 340 m/s​

Answer 1

speed=frequency × wavelength

frequency =1/time period

340=(1/0.01 )*(wavelength)

340*0.01 = wavelength

3.4m = wavelength

Answer 2

Speed= wavelength * frequency

Speed = wavelength *1/t

Speed* time period =

wavelength

340*1/100 =3.4m

So wavelength =3.4m
