    Visible light wavelength discrepancy on the EM spectrum?

    yes! thanks thanks ;) did not consider.

    Visible light wavelength discrepancy on the EM spectrum?

    oh ok, but shouldn't it be close to 10^-9 for nm? at least when the base is not a zero decimal number? sorry, really bad with math as well...

    Visible light wavelength discrepancy on the EM spectrum?

    well it goes from 10^7 to 10^-14 on the gamma-end of the spectrum. distances between the numbers on the picture are equal and "visible light" is clearly marked at 10^-6 and it says next to it "1 µm" so no decimal notation there.

    Electromagnetic wave propagation/dissipation

    Hey all, just wondering over a very naive question but I couldn't really find the answer by looking through the web. So electromagnetic waves are self sustaining and they don't lose energy while traveling through space, except if the photons they're made out of do "collide" with matter which...

    Visible light wavelength discrepancy on the EM spectrum?

    ah you're right there, that was my own stupidity. however in that book I have, they really noted it at 1x10^-6 m, but I guess that's just a mistake then... Thank you

    Visible light wavelength discrepancy on the EM spectrum?

    Hello all, I'm not all too familiar with the electromagnetic spectrum, nor generally with physics but there is something that keeps me up. I learned, and also read now everywhere that visible light (to humans) lies in the wavelength range of about 400-700 nm. No I have a science book here...
