Mirror formula is the relationship between object distance (u), image distance (v), and focal length.
Derivation
The figure shows an object AB at a distance ‘u’ from the pole of a concave mirror. The image A1B1 is formed at a distance ‘v’ from the mirror. The position of the image is obtained by drawing a ray diagram.
Consider the D A1CB1 and D ACB
[when two angles of D A1CB1 and D ACB are equal then the third angle
But ED = AB
From equations (1) and (2)
If D is very close to P then EF = PF
But PC = R, PB = u, PB 1 = v, PF = f
By sign convention
PC = -R, PB = -u, PF = -f and PB 1 = -v
Equation (3) can be written as
Dividing equation (4) throughout by uvf we get
Hence, equation (5) gives the mirror formula.

- Personal Computers
- Servers
- Networking Hardware
- General Hosts
Networking can be classified into three types:

VAN DE GRAAFF Generator
Van de graaff generator is used to generate high voltages of the order of a few million volts. This results in generation of large electric fields for experimental purposes.
Principle
- The inner sphere has a higher potential than outer if the charge q is positive.
- If the two spheres are connected through a wire, the charge will flow from high to low potential.

Law of Dominance states that dominant alleles always mask the recessive alleles. In heterozygous condition always dominant allele is expressed in F1 generation. The characters that appear in an F1 generation are called as dominant alleles and which are not expressed are recessive. For example, a cross between any pair of contrasting characters, always dominant character is expressed. But this law is not universal always.
