Question

The speed of a sound wave in sea water is 1500 m/s. If this wave is transmitted at frequency 10 khz, what is its wavelength?.

Answer 1

$\bf \dag \boxed{ \lambda \{ \rm wavelength \} = \dfrac{speed}{frequency} }$

So:-

$\dashrightarrow\lambda \{ \rm wavelength \} = \dfrac{150 \cancel0}{1 \cancel0}$

$\dashrightarrow\lambda \{ \bf wavelength \} =150m$
