IB Physics: Activity: Multiple slit interference

A diffraction grating is a piece of glass with many (thousands) very fine lines printed on it to form a series of parallel slits. Each slit diffracts the light causing it to spread out. The light from each slit overlaps so the waves interfere creating areas of light and dark.You should see a set of bright dots, each dot is an interference maxima caused when the light from the slits adds up.The equation for the maxima...
