WebQuestion. For the same grating as the previous question, a converging lens of focal length 80mm is placed after the grating with its axis along the second-order light at 550nm, and a detector at the focal point. Calculate the separation on the detector between light at 550 nm and 551nm wavelengths; give your answer in micrometers to 1 d.p. WebHow does the focal length affect magnification? On a full-frame camera, 50 mm gives 1:1 magnification. Relative magnification of a lens is the focal length over 50 - e.g. a 100mm lens gives 2x magnification …

Or, v= uf u−f. Putting value of v in equation 1. Magnification m = f f−u. Hence this is the relation between the magnification and focal …

WebIt is an equation that relates the focal length, image distance, and object distance for a spherical mirror. It is given as, 1 i + 1 o = 1 f. i= distance of the image from the lens. o= distance of the object from the lens. f= focal length of the lens. The lens formula is applicable to all situations with appropriate sign conventions.

WebIn the equation for(f/#) w, m represents the magnification (ratio of image to object height) of the lens.Note that as m approaches zero (as the object approaches infinity), (f/#) w approaches f/#.
