If a wave has a frequency of 0.4 Hz and a wavelength of 15 m, what is its

velocity?

Answer: 6.0m/s

Explanation:

Given that:

Wavelength (λ) = 15m

Frequency F = 0.4Hz

Velocity V = ?

The wave velocity is the distance covered by the wave in one second. It is measured in metres per second, and represented by the symbol V.

So, apply the formula V = F λ

V = 0.4Hz x 15m

V = 6.0m/s

Thus, the velocity of the wave is 6.0m/s
