Mirror Formula and Magnification - GeeksforGeeks

WebFrom this definition, it can be shown that the AFOV of a lens is related to the focal length ( Equation 1 ), where f f is the focal length and H H is the sensor size ( Figure 1 ). (1) AFOV = 2×tan−1( H 2f) AFOV = 2 × tan − 1 ( H 2 f) Figure 1: For a given sensor size, H, shorter focal lengths produce wider AFOV’s. 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... WebMar 25, 2024 · Let the Focal length of mirror = f So, the object distance, u = -2f The formula to calculate image distance we use mirror formula as, 1 / v + 1 / u = 1 / f Therefore, 1 / v + 1 / -2f = 1 / f 1 / v = 1 / f + 1 / 2f = 3 / 2f or v = 2f / 3 Magnification is given as, m = – v / u = - (2f/3) / (-2f) = 1/3 Problem 2. only strong survive
