New electromagnetic spectrum images

EM Spectrum: IR Visible Light UV

I've just finished a set of images showing wavelengths of visible light, many with infrared and ultraviolet on either side. See them on my Pictures of Optics, Light & Colour Gallery. They show waves that differ in wavelength by 50nm, making this a linear array. This is different from how the EM spectrum is usually shown, but I think that it makes things easier to visualise (at least for this narrow band of wavelengths). To give you an idea of scale, an AIDS virus is about 120 nm across. Visible light ranges from about 400 nm to 700 nm, making it too coarse to see viruses, which is why we need an electron microscope to see them.
