Producing EM waves in laboratory

  1. Nov 19, 2015 #1
    1. The problem statement, all variables and given/known data
    I am just wondering is there any apparatus available to produce EM waves of arbitrary wavelength and intensities? If not, how I can produce an EM wave of my desired wavelength in the laboratory?

    2. Relevant equations


    3. The attempt at a solution
    I completely have no idea :(

    Yes, the light switch. :biggrin:

    Seriously though. The spectrum that you get is going to be based on the apparatus that you're using. You're not going to get X-rays from a light bulb and you're not going to get visible light from a radio transmitter. There isn't a single apparatus that will give you every possible EM wavelength.
