We can't see the graph.
But is has to show that wavelength and frequency are inversely

That's because their product is the speed of the wave.
If the graph doesn't show that, then the graph is wrong.
The data from our experiment.

-Vibilities
Answer:
c)Average acceleration is always equal to the change in velocity of an object divided by the time interval.
Explanation:
Because average acceleration= a2+a1/2
Which is equal to change in velocity which is a time rate of change of velocity v-u/t which actually explains average acceleration
