Bobby creates a wave at a constant speed of 24 m/s. As frequency changes, what happens to the wavelength?
If we increase the frequency from 8m/s to 10/s. Wavelength will go from ___ to _____?
Frequency and Wavelength have an inverse relationship. When one goes up, the other goes down.
In the question, Wavelength will drop from 3 to 2.4
