Rain is falling into a puddle, you notice the distance between each ripple is 0.05m. The waves are spreading out at a rate of about 0.5m/s, what is the frequency of the rain dropping?

The frequency of the wave of the rain dropping is 10 Hz.

The given parameters;

  • wavelength of the rain drop, λ = 0.05 m
  • speed of the wave, v = 0.5 m/s

The frequency of the wave of the rain dropping is calculated as follows;

v = fλ

[tex]f = \frac{v}{\lambda} \\\\f = \frac{0.5}{0.05} \\\\f = 10 \ Hz[/tex]

Thus, the frequency of the wave of the rain dropping is 10 Hz.
