Diffraction occurs when waves - including electromagnetic waves (i.e., light) - pass through a narrow opening about the same size as or a little larger than the wavelength. The waves bend and expand around the edges of the slit. Depending on the slit width d, the diffraction (and subsequent interference pattern) may appear very different. Explain how the diffraction grating equation d sin 8m = m. λ illustrates this.
