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.

Answer 1

[AI-generated answer — Bot]

The frequency of the wave would decrease.

Answer 2

A student performs an experiment by ringing a bell in the air and in a pool and measuring the time it takes for a friend to hear the bell. In one or two sentences, make and justify a hypothesis on which medium the friend would hear the bell the fastest.(2 points)
