Ch. 27. Interference and the Wave Nature of Light Up to now, we have been studying geometrical optics , where the wavelength of the light is much smaller than the size of our mirrors and lenses and the of the light is much smaller than the size of our mirrors and lenses and the distances between them. The propagation of light is well described by linear rays except when reflected or refracted at the surface of materials reflected or refracted at the surface of materials. Now we will study wave optics , where the wavelength of the light is comparable to the size of an obstacle or aperture in its path. This leads to the wave phenomena of light called interference and diffraction . I am the blue Morpho butterfly, and I love physics!
