WebThe focal length of an optical system is a measure of how strongly the system converges or diverges light; it is the inverse of the system's optical power.A positive focal length indicates that a system converges light, while a negative focal length indicates that the system diverges light. A system with a shorter focal length bends the rays more sharply, … Webc. Focal length which is represented as ‘f’. ... Magnification can also be related to the image distance and object distance; therefore it can also be written as: ... Solved Example for You. Q.

"WebA lens focal length that’s greater than 50mm is considered a long focal length. This view is narrower than the normal view we’re accustomed to when paying bare attention. An image taken with a 100mm telephoto lens will have a much smaller section of coverage than a normal or wide-angle field of view. " - Focal length and magnification relation
