Pearson requires determination of the wavelength of light from a laser or other light source using a diffraction grating; the shared resource also includes Young's slits as broader generic revision.

Interference: Young's slits and diffraction gratings
Measure double-slit fringes and matching diffraction orders, then determine and compare the wavelength of laser light using two methods.
This simulation supports preparation and data-analysis practice. It does not replace carrying out real practical work.
