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 ...

A laser pointer shining on a diffraction grating or CD creates a series of diffraction spots depending on the spacing of the lines or pits in the grating or CD and the wavelength emitted by the laser.

One of the coolest things about physics is that the same basic concept can pop up in several seemingly unrelated things: say, a CD, the seed shrimp’s antennae, certain fossils in the Burgess shale, ...

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 ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...

First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...

Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...

Inprentus, a leading manufacturer of high-precision diffraction gratings, has released a new white paper showcasing the unique properties of a grating delivered to the European X-ray Free Electron ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...
