*Edit: Nevermind, I realize where I went wrong! Homework Statement The following graph shows the kinetic energy of the most energetic photoelectrons as a function of the frequency of light falling on the cathode in a photoelectric cell. http://img208.imageshack.us/img208/3421/fwby.jpg...

Green and orange light pass through a diffraction grating that contains 6000 lines/cm. Compare the appearance of the fringe at m = 0 with all the others. So far I've only dealt with light with one wavelength, so I just want to make sure I have the right thought process here for two...

That helps, thank you for the response :)

I don't know if this would be considered a homework problem, so I hope I'm posting in the right place. I'm working through an independent learning course and just needs some help with the terminology in the book. It started expressing wavelengths in 1/2λ, and I can't find an explanation why...
