WebThe Lens formula is applicable for convex as well as concave lenses. These lenses have negligible thickness. It is an equation that relates the focal length, image distance, and … WebFocal length ( f) and field of view (FOV) of a lens are inversely proportional. For a standard rectilinear lens, FOV = 2 arctan x 2 f, where x is the width of the film. When a photographic lens is set to "infinity", its rear principal plane is separated from the sensor or film, which is then situated at the focal plane, by the lens's focal length.
WebThe magnification is approximately 0.67 0.67, meaning that the image is smaller than the object (since 0.67 < 1 0.67 < 1) and the image is virtual (since 0.67 0.67 is positive). Example of...
