2) So, for n < 2, the focal length of a plano-convex thin lens will be greater than the radius of curvature, and for n > 2, the focal length will be less. Most optical materials have an index of refraction in the range of 1.3 to 1.7 for visible light, so for most lenses, the...
Focal lengthFourier transformA procedure for the measurement of focal length and radius of curvature of a lens using coherent gradient sensing system and Fourier transform fringe analysis technique has been demonstrated. Light from the laser illuminates the specimen and the wavefront emerging from the ...
To find the radius of curvature of a convex mirror when its focal length is given, we can use the relationship between the focal length (f) and the radius of curvature (R). The formula is:
