Answer
B
Explanation
The frequency of a wave is the number of vibrations produced per unit time. In this context, moving one end up and down more swiftly would bring about a greater number of cycles every second, thereby bringing about a higher frequency. Thus, altering how rapidly you move the slinky up and down will alter the frequency of the wave. Other options like pulling the slinky tighter to change the medium do not influence the frequency of the wave. That would change the speed of the wave, but not the frequency. Lastly, moving one end up and down further alters the wave's amplitude, not its frequency; and of course, it is completely feasible to change the frequency of a wave on a slinky. Therefore, only the approach specified in option b would directly alter the wave's frequency.
