Homework Help: Wavelength (Colours) and line spectra.

  1. Jan 20, 2008 #1
    1. How does wavelength affect line spectra (the spacing)?

    I did some research and found the wavelength of green light to be 510 nm and red light to be 650 nm. So for the experiment I looked through slits (such as 2, 2, 6 (which represents 2 slits, 2 points wide, and separated by 6 points) where 1 point is 0.000352777 metres) )such and observed green light on top and red light on the bottom and compared the lines. I noticed that green light lines were further apart than red light lines. What does this tell me about their wavelengths? THanks

    I don't really understand your experiment, but it could be that it is because your eyes can't see red very well.
