C3 activity: Multiple slit interference
Having become familiar with Young's double slit, now you will observe the interference effects caused by a diffraction grating. Diffraction gratings can be used to produce spectra and measure the wavelength of light. To do this, you will need to derive the equation for the angles that give maximum intensity. Increasing the number of slits improves resolution; you'll explore this too. Topics: multiple slits n2kLevels:...
