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 \} = (speed)/(frequency) }`

So:-

`\dashrightarrow\lambda \{ \rm wavelength \} = (150 \cancel0)/(1 \cancel0) \\`

`\\ \\`

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