Focal length physics
WebThe result is a telescope with a focal length much greater than the length of the telescope itself. Figure 16.12 This diagram shows the design of a Schmidt–Cassegrain telescope. … WebFocal length Focus is defined as the point through which the reflected light rays pass (or appear to pass) when incident light rays are parallel to the principal axis. It is located at the midpoint of pole and centre of curvature. The distance between the pole and the focus of the mirror is called the focal length of the mirror. Hence, f = 2 R
