Question

The formula vw​=f⋅λ describes the relationship between the speed of a wave (vw​), its frequency (f), and wavelength (λ).

For example, if a wave has a frequency of 120 Hz and a wavelength of 5 m, it would have a speed of 600 m/s.

In one or two sentences, describe what would happen to the frequency of this wave if the wavelength is increased to 10 m but the speed stays the same at 600 m/s.

Answer 1

Use f = v/λ. If v = 600 m/s and λ = 10 m, then f = 600/10 = 60 Hz, so the frequency halves (from 120 Hz down to 60 Hz).
