Focal point vs radius of curvature
http://physics.bu.edu/~duffy/PY106/Reflection.html WebNote: This calculator follows the standard sign convention for the optical radius of curvature where if the vertex of a surface lies to the left of the center of curvature the radius of curvature is positive, and if the vertex lies to the right of the center of curvature the radius of curvature is negative.

WebPhysics Chapter 26. 1) State how to draw the three rays for finding the image position due to a curved mirror. Ray 1 leaves the top of the object and is drawn such that it is parallel to the axis; therefore after reflection it must pass along a line through the focal point. Ray 2 leaves the top of the object and is made to pass through the ... WebMay 23, 2024 · Radius of Curvature. Since the focal length of a lens is directly related to its refractive index, as well as, the curvature of its surface (or surfaces), it is important to understand exactly how this shape is …
WebFeb 22, 2015 · The radius of curvature R of a curve at a point is the radius of the circular arc which ''best'' approximates the curve at that point. Here ''best'' means that the system given by the curve equation and the circle equation have a … For a thick lens (one which has a non-negligible thickness), or an imaging system consisting of several lenses or mirrors (e.g. a photographic lens or a telescope), there are several related concepts that are referred to as focal lengths: Effective focal length (EFL) The effective focal length, also sometimes called …
WebPossible Answers: The focal point cannot be found from the given information Correct answer: Explanation: Since the mirror is concave, the focal point will be in front of the mirror. The focal length is equal to one half of the radius of curvature. R c is the radius of curvature. Plugging in 0.85m for R c allows us to solve for the focal length.
