Yes, radius of curvature is longer than focal length for both types of lenses ( O1 and O2 are the centers of curvature, F is focal point): Yes, curvatures of lens surfaces ( R1 and R2) along with refractive index of lens material ( n) affect its focal …

The Importance of Focal Points in Photographic Composition

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. WebEach mirror has a radius of curvature r (which is infinite for the plane mirror) and a focal length f = 1 2 r.

Higher angles of curvature lead to shorter focal lengths due to the fact that light waves are refracted at a greater angle with respect to the optical axis of the lens.

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 …
