The frequency of a wave is 40hz and it's wavelength is 8.0m find the speed of sound

Answer 1

$\huge\bf\green {Hey \: there!}$



▶ Given :



i) Frequency of a wave ( f ) = 40 Hz



ii) Wavelength of a wave (  λ ) = 8 m




▶ To Find :



The speed of the wave




▶ We know that :



Speed ( v ) = Frequency ( f ) × Wavelength ( λ )



=> v = 40 Hz × 8 m


=> v = 320 m / s



$\large {\boxed {\boxed {\pink {\sf {Therefore, Speed \: of \: the \: wave = 320 \: {\dfrac {m}{s}}}}}}}$
