Webbmagnification, in optics, the size of an image relative to the size of the object creating it. Linear (sometimes called lateral or transverse) magnification refers to the ratio of image … Webb11 maj 2024 · The eyepiece is equally easy to figure out. From the equation for magnification we have M = f O /f e, and we want the value of f e-min to get us to M max = D O so then D O = f O /f e-min, and therefore f e-min =f O /D O. Since the f-ratio f R =f O /D O then we have, quite simply, f e-min = f R Wow. Do you see what this is saying?
