Description of 🌈 Diffraction Grating Slides by Rainbow Symphony

Makes the study of light and color fun and unforgettable. Features highly efficient embossed Holographic Optical Elements. Used for the direct viewing and analysis of spectra from different gas tubes and other light sources. Spectrum produced from our gratings is the brightest possible with a minimum of distracting visual noise. Great for overhead projector or 35mm slide projectors

Great "Science Gear " for the price

I actually bought these as gifts for science parties and my little one has been fascinated by them ever since. They work flawlessly and break down different light sources into their respective spectra. Try looking through them at car headlights, smartphone screens, various lamps, and just about anything that's lit.

Pros
  • Nice packaging
Cons
  • Can't remember

These are great for understanding how lighting works. If you look through the foil and a little to the side at a lightbulb, you'll see a stretched version of the light that looks like a rainbow. Colors (reds, greens, and blues) that indicate that the light comes from the phosphors that emit those colors. While these lights claim to be "full spectrum," the actual spectrum is a discrete sampling of frequencies that combine to allow us to see as if the full spectrum were present. Various…

Pros
  • Free for educational purposes
Cons
  • Unsure

There is confusion as to how this product works. This is a "uniaxial" diffraction grating, meaning you see a point light source. and you see an iridescent "smearing" of the color spectrum produced by that light appearing to both the left and right of the point source. Hence the name "linear" diffraction grating because everything is a flat line. However, you NEED to hold it VERY close to your eye (about an inch or so) and you probably still need to be looking in one direction to see the…

Pros
  • Easy installation
Cons
  • There are other interesting options.
