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.
7th grade level pls help 2 sentences preferred

Answer 1

If the wavelength doubles to 10 m while the speed stays 600 m/s, the frequency becomes f = 600 ÷ 10 = 60 Hz. So the frequency halves from 120 Hz down to 60 Hz.
