Deduce the relation between wavelength, frequency and speed of sound.

Let ‘λ’ be the wavelength and ‘T’ be the time period. ‘v’ be the speed of sound wave.

⇒ Wave travels distance ‘λ’ in time ‘T’. (Because wavelength is the distance travelled by particle during particular time).

WE know that;

⇒ (Distance travelled in time ‘T’ = wavelength (λ).)

⇒

(∵ Frequency (ν) = )

∴ Speed of sound wave = Frequency × Wavelength
