WebMar 25, 2007 · elitespart. 95. 0. 1. The radius of Earth is 6.40 x 10³ km. The moon is about 3.84 x 10^5 km away from Earth and has a diameter of 3475 km. The Pacific Ocean surface, which can be considered a convex mirror, forms a virtual image of the moon. What is the diameter of that image? WebFor example, a typical zoom lens might have a focal length of 18-55mm, or 24-70mm. Focal length comes from the distance between a specific part of a lens (the “optical centre”) and the image sensor (or film plane) where the image is recorded. The wider the angle of view that a lens offers, the smaller this distance, and the lower the number.

The article specifies that the horizontal FOV is 47°, so we have to use. A = 640/2 = 320, a = 47°/2 = 23.5°, which give F = 736 pixels. As your sensor size is given in pixels (assumed square pixels!), your focal length will also be in pixels.
