Atmospheric dispersion and its effect on the Airy pattern By Andre Paquette, andre at astrogeeks dot com Introduction . The atmosphere acts like a prism, refracting star light so that the apparent elevation of the star changes. This effect is dependent on the actual elevation, the temperature, pressure, and the wavelength of the light. The differential refraction by wavelength is called ...
Atmospheric Dispersion (also see Atmospheric Refraction) In addition to refraction, light coming through the atmosphere (and most other media) suffers from dispersion, which is a rainbow-like effect caused by different colors or wavelengths of light being refracted by different amounts. In general, shorter wavelengths (e.g., blue and violet) are refracted more and longer wavelengths (e.g ...
