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 ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...

Remember to keep your fingers away from the grater when holding the food. Stop grating when there is a small piece of food left. Do not try to grate it all. Can you tell the difference between a ...

Metasurfaces have the potential to fundamentally improve optical systems in our everyday lives. By controlling light more precisely, they drive compact, multi-functional solutions. Researchers have ...

It's convenient, versatile, and adds a deliciously melty texture to the spread. But as easy as grating cheese can be with ...
