We call this a diffraction grating and it makes a nice interference pattern. Let me see if I can make a sketch of waves passing through just two openings. Yes. This is just a sketch. But here you ...

It’s the same effect you see on the bottom of a CD! You can 3D print a functional diffraction grating, too, with the right techniques, as it turns out! The average 3D printer can’t recreate ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

But how do you make a 3D print sparkly? Turns out, he had used a diffraction grating before to make rainbow-enhanced chocolate. The method turns out to be surprisingly simple. Using a diffraction ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

Rotating the diffraction grating controls which wavelengths of light reach another mirror, which in turn focuses these wavelengths onto a photodetector, such as a charge-coupled device.

McPherson's SXR spectrometer, Model 251MX, is now available with improved efficiency over a wider range. A new diffraction grating is available! The new Gold coated diffraction grating is ideal for ...

The Dittoscope is essentially a huge diffraction grating: a flat surface that is grooved in a regular pattern. (A cross-section would look like a series of regular waves.) Astronomers have used ...

One essential component used in modern astronomical science is the diffraction grating. Its role is to spatially spread incoming light into its constituent frequencies, similar to how a glass ...
