The focal length of spherical mirrors

The focal length of the mirror (explicitly state the algebraic sign in your answer) the radius of curvature of the mirror the type of mirror (converging or diverging) spherical mirrors refraction mirrors. Spherical mirror equation the equation for image formation by rays near the optic axis (paraxial rays) from the geometry of the spherical mirror, note that the focal length is half the radius of curvature: show: as in the case of lenses.

  • Spherical mirrors - posted in reflectors: is their a rule for what focal length a spherical mirror will work as well as parabolic (in terms of focal length) do any think that a 6 f/10 would pass thanks jim.
  • Phys 63: optical elements: prisms, lenses and spherical mirrors 1 opening items 11 module introduction 12 fast track questions 13 ready to study 2 refraction by a prism we therefore define f as the focal length of the mirror and the point f as the mirror's focal point.
  • Concave mirrors have positive focal length, and convex mirrors have a negative focal length distances are positive if they are in front of the mirror, and negative if they are behind all measurements are made along the principle axis from the surface of the mirror.
  • Now let us consider the focal length of a mirror for example, the concave spherical mirrors in figure 2 rays of light that strike the surface follow the law of reflection.
