Question

If the speed of a wave is 335km/s and has a wavelength of 600km what is its frequency?

Answer 1

The frequency is 0.558 s⁻¹.

The wavelength λ is the distance between successive peaks in a wave.

The frequency `f` of a wave is the number of complete waves that pass a point in a given time.

The formula relating the frequency `f` and wavelength λ is

`fλ = v or f = v/λ`

where `v` is the speed of the wave through the medium.

In your case, `λ` = 600 km = 600 × 10³ m and `v` = 335 km·s⁻¹ = 335 × 10³ m·s⁻¹.

∴ `f = v/λ = (335 × 10³"m·s⁻¹")/(600 × 10³"m")` = 0.558 s⁻¹
