If you truly want to understand SWR, I recommend you pick a frequency and make up a 1/4, 1/2 and 1 wavelength sections of 50ohm coax.
Then measure the SWR at those points into various different resistive loads, like 10, 25, 50, 75, 100, 150 and 200 ohms. I think you will find the results very interesting.
