Mr Doner, I don't get why the frequency doesn't change when the wavelength changes- Doesn't frequency increase when the wavelength decrease and vice versa? Is it because one of the variable has to stay constant in the formulas? Also thank you soso much for these videos!! You're a lifesaver for us all
In a given medium, when you increase the frequency, the wavelength decreases, thus keeping the speed constant. If we change media, that changes the speed, however, the frequency will be the same in both media, only the wavelength will change.
It is displacement against position. If it were displacement and time, a cycle would be a period not a wavelength. This is explained later in the video.
I don't get why speed remains unaffected intuitively. Say I am shaking my hand real fast, surely the speed at which I am shaking it is faster than when I am shaking it slow up and down?
You've honestly saved my life with this video!! Thank you so much!
You made my study days much easier with these interesting videos Mr.Doner.
I want to thank you very much. You raised my chances for a good grade at this year finals.

Glad it helped!
Totally appreciate this. Thanks so much for this upload.
My pleasure!
Thank you, Mr.Doner
Thank you very much!!! So helpful!!!
You are awesome, thank you.

Your first graph should be labeled with units on axis, if it was a time, it would not be a wavelength but period.right?
