Focal length and magnification relation

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, … WebFig. 1 The relation between the image distance S ’, object distance S and focal length f is given by 1/S + 1/S ’ = 1/f Suppose the lens produces a sharp image of the candle at the two positions as shown in fig1.

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. WebFocal Length controls the field of view in front of the lens. A longer focal length has a narrower field of view than a shorter one. Behind the lens, it is designed to project this … Web9 Magnification ...

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.

WebTo obtain this type of numerical information, it is necessary to use the Mirror Equation and the Magnification Equation. The mirror equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f). The equation is stated as follows: 1/f = 1/di + 1/do WebMagnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification". …
