I measured the voltage drop to light several led`s of approximately the same size using the diode mode of my Bryman multi-meter. The red one used the least amount of energy to light and was the brightest, but the yellow one used the most. The green one was in the middle.

Nice explanation and I like your examples. Just recheck your concept of Crest and trough.

@mekahfagan4012 4 жыл бұрын

The crest should be at the top where the 5 is because the crest is the highest point the medium rises to and the trough should be at -5 because that is the lowest point the medium drops to so you made a small error there at 0:50 in the video but otherwise you provided a good explanation! 👍😀

I have around 3500 data points that create a wave. My task is to detect the maximum range of the wavelenght, so basically the largest distance from the crest to the trough and since my wave is pretty irregular I was wondering if there is a method to calculate and detect it. Take into account that between the crest and the trough there are also points (values) that I would of course exclude since they are not my crest nor my trough point.
