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 ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode ...

Obviously the wavelength of a laser can’t be measured with a scale as large as that of a carpenter’s tape measure. At least not directly and that’s where a Compact Disc comes in. [Styropyro] uses a CD ...

The grating bends red light in a different way from orange light, which bends a little differently from yellow light and so on, spreading the many wavelengths into a rainbow spectrum. Rotating the ...
