AS Physics Edexcel A Level. Double or triple lesson. Introducing the idea of diffraction gratings and how to find the slit width for a grating. Derivation of the nλ = d sin(θ) formula and how to find ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

This lesson is on the using the diffraction grating formula We then look at how the formula is used to determine the wavelength of light, before the students perform a practical themselves, in an ...

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 ...

Diffraction gratings separate different wavelengths of light using a periodic pattern embedded in the grating. The diffraction pattern can affect the amplitude and/or phase of the incident light as ...

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 ...
