Object distance (u), image distance (v) and focal length (f) of a spherical lens are related as:
1/v – 1/u = 1/f.
The formula is a relation between the object distance u, image distance v and the focal length from the pole of the concave mirror. The formula is valid for the images in a convex mirror and even for the images in the lens.
We consider the image formed by a concave mirror whose focal length is f and whose radius of curvature is r = 2f.
Let P be the pole of the concave mirror. Let P, F , C be the pole, focal point, and centre of curvature along the principal axis. So, PC = 2PF , as r = 2f.

- Resistivity is the physical property of a particular substance which is having particular dimensions.
- Resistivity is only proportional to the nature and temperature of the particular material.
- ρ = (R×A)/L
R = Resistance, L= Length, A = Cross-sectional area
-
The SI unit of resistivity is Ohms-meter.
-
Electrical resistivity measurement is used as a quality control test for calcareous soil.
