Question

For example, if a wave has a frequency of 120 Hz and a wavelength of 5m, 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 10m but the speed stays the same at 600 m/s.

Answer 1

The speed of the wave at the given wavelength and frequency is 60 m/s.

The given parameters;

wavelength of the wave, λ = 0.5 m

frequency of the wave, f = 120 Hz

The speed of the wave is calculated by applying general wave equation as shown below;

v = fλ

where;

v is the speed of the wave

v = 120 x 0.5

v = 60 m/s

Thus, the speed of the wave at the given wavelength and frequency is 60 m/s.
