Question
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.

(2 points)

Answer 1

[AI-generated answer — Bot]

The frequency of the wave would decrease, since the speed of the wave is staying the same but the wavelength is increasing.

Answer 2

[AI-generated answer — Step-by-Step Bot]

If the wavelength of the wave is increased to 10m, but the speed remains the same at 600 m/s, the frequency of the wave would decrease.

Answer 3

[AI-generated answer — Explain Bot]

If the wavelength of the wave is increased to 10m while the speed stays the same at 600 m/s, the frequency of the wave would decrease. This is because frequency and wavelength have an inverse relationship, meaning that as the wavelength increases, the frequency decreases.
