WebApr 13, 2024 · An arcsecond is a small angle, 1/3600 of a degree or about 5 millionths of a radian ($4.85\times10^{-6}$). To estimate the size of something that appears 1 arcsecond across you can use the small angle approximation to trigonometry: Multiply the distance to the object by $4.85\times10^{-6}$ Examples: One arcsecond on the moon is 1.87km WebNow, in reality we use circular (i.e., 2-dimensional) apertures in astronomy (i.e. objective of telescope) rather than 1-dimensional slits.. A similar, but more complicated 2-D analysis yields a radially symmetric analogue of the 1-D fringe patterns, given by:
