is that A B C or D?
That is response option A.
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.

If the wavelength of the wave is increased to 10m while the speed remains constant at 600 m/s, the frequency of the wave would decrease.
make that sound like a 7th grader
If the length of the wave gets longer to 10m while the speed stays the same at 600 m/s, the number of times the wave repeats in a second (frequency) would go down.
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)
I hypothesize that the friend will hear the bell faster in the air compared to in the pool because sound travels faster in air than in water, therefore reaching the friend's ears more quickly.
make that sound like a 7th grader
I think that the friend will hear the bell faster in the air because sound travels faster through air than through water, so it can reach their ears more quickly.
