WebDawes' limit is a formula to express the maximum resolving power of a microscope or telescope. [1] It is so named after its discoverer, W. R. Dawes , [2] although it is also credited to Lord Rayleigh . The formula takes different forms depending on the units. R = 4.56/ D. D in inches, R in arcseconds. The imaging system's resolution can be limited either by aberration or by diffraction causing blurring of the image. These two phenomena have different origins and are unrelated. Aberrations can be explained by geometrical optics and can in principle be solved by increasing the optical quality of the system. On the other hand, diffraction comes from the wave nature of light and is determin… dungeons and dragons 5th edition game
