A wave has a frequency of 500 Hz and a wavelength of 2 cm. What will be its velocity?

5 m/s

10 m/s

15 m/s

None of these

Wave velocity $v$ is calculated using the formula $v = f lambda$ , where $f$ is frequency and $lambda$ is wavelength.

Substituting values: $v = 500 times 0.02 = 10 , text{m/s}$ .
