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 central result of our diffraction experiments is the observation of high-contrast interference for all gratings, where the contrast reaches its maximum when the interference minima approach the ...

What happens when a wave passes through some opening? It diffracts - or you like, you could say "bends". If the size of the opening is comparable to the wavelength of the wave, the bending can be ...

Scientists have demonstrated that atoms can exhibit wave-like behavior, challenging long-held assumptions that experiments of this nature were impossible and opening new doors in quantum physics. The ...

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 ...

Quantum physics tell us that even massive particles can behave like waves, as if they could be in several places at once. This phenomenon is typically proven in the diffraction of a matter wave at a ...

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 ...

Modern Canadian plastic money (specifically the Frontiers series) has a diffractive element in it as a security feature. When a laser beam shines through the maple leaf on the bill, it produces a ...

THE June issue of the Journal of the Franklin Institute contains two interesting letters from the second volume of the Transactions of the American Philosophical Society (1786), from which it would ...
