- For a concave mirror, the focus is located at a distance of half the radius of curvature from the mirror's surface. - Mathematically, it can be expressed as: F=R2 - Here, R is the radius of curvature. 2. Principal Axis: - The principal axis is an imaginary line that runs throu...
What is the potential difference between the centers of two rings separated by a distance of 1 m? Give a definition of the following term: Hooke's Law. What are the basic concepts of physics? Explain why the distance from mirror to object is the radius of the curvature. What term denotes...
Therapeutic discharge shoe e.g. orthopedic shoe, for e.g. aged person, has inner sole including convex part bulged towards concave part and with curvature radius lower than that of arch to define space between convex part and metatarsus ...
The convex part is bulged in the direction of the concave part, and has a radius of curvature lower than that of the arch so as to define a space between the convex part and a metatarsus of the foot at or near a front end (31) of the convex part....
