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...
What is the relation between the focal length and radius of curvature for concave mirror? Answer: The focal length is ‘f’ and radius of curvature is ‘R’ of concave mirror and f = R/2.Question 12: Give two uses of concave mirror. Answer: Concave mirror is used by dentist and in ...
To find the relationship between focal length (f) and radius of curvature (R), we can follow these steps:1. Understanding the Concepts: - A lens or mirror can be thought of as a part of a sphere. The radius of curvature (R)
Suppose she wants an erect with a magnification of 2.00 when the mirror is 1.25 cm from a tooth. (Treat this problem as though the object and lie along a straight line.) (b) What must be the focal length and radius of curvature of this mirror? 513 views...

to see you included exceptions to your NEVER comment. I've ground and polished a few mirrors and I tracked the focal length with a spherometer, "wet" mirror solar test (at the focal point) before the glass was polished, and polished mirror "flashlight" test (at the radius of curvature)...
