A rope is stretched out before you; one end is in your hand and the other is attached to the wall $4$ meters ahead. You are moving the rope up and down creating a transverse wave along the length of the rope. $[$For those who have been to an equipped gym, think "battle ropes"$]$ You are creating a harmonic. The questions are all in comparison to the speed, frequency, wavelength, amplitude, and harmonic you are initially producing. $($If there are multiple correct answers for each question, you need provide only one.$)$ Assuming you have the power to change any physical aspect of the rope as well as the ability to change how you move$/$interact with the rope, how can you

$($a$)$ Increase the speed of the wave in the rope?

$($b$)$ Increase the frequency of the wave?

$($c$)$ Increase the wavelength of the wave?

$($d$)$ Increase the amplitude of the wave?

$($e$)$ Increase the harmonic? $($For example, from the $2^{3i3}$ harmonic to the $3^{3x^{23}}$ harmonic$)$
