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


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.

Increase in wavelength will cause decrease in frequency. When wavelength doubles, the frequency of the wave will reduce to half of its value.

WAVE SPEED

The wave speed is the product of wave frequency and its wavelength.

v = f⋅λ

  • v = the speed of a wave
  • f = frequency
  • λ = wavelength

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.

if the wavelength is increased to 10m but the speed stays the same at 600 m/s. That is,

λ = 10m

v = 600 m/s

v = f⋅λ

Substitute f and v into the formula

600 = 10f

f = 600 / 10

f = 60 m

The frequency of the wave is reduced to half of its value.
