1. The problem statement, all variables and given/known data hi i've just been doing labs today on data aquisition looking at current voltage characteristics, one thing that i did was look at the forward(working) voltage for a red, green and white LED. Red = 1.5V Green = 1.8V White = 2.6V when i asked the demonstarter why this was he said that we arent asked to know this to write in our lab books and so it didnt matter, but i do want to know why. ive looked on the web and i think it has something to do with the wavelength produced and that each one might need slightly more energy to get the lower wavelength [cause E=hc/[tex]\lambda[/tex]] and white light needs alot more at it isnt monochromatic. is any of this thinking right?
