The fact that chemical reactions produce electrical effects was discovered accidentally in 1791 by Luigi Galwani, professor of anatomy at the University of Bologna, Ital..

The ratio of the height of the image to the height of the object is called the linear magnification. It is denoted by the letter m. While deriving the mirror formula it has been proved that D ACB and D A 1 CB 1 are similar and so also D FB 1 A 1 and D FED are simila..

Radius of Curvature is the radius of the sphere of which the mirror is a part. It is represented by the letter ..

It is the center of a lens. It is denoted by the letter O. A ray of light passing through the optical center of a lens does not suffer any deviation. It is also referred to as optic cent..

Optical Center - It is the center of a lens. It is denoted by the letter O. A ray of light passing through the optical center of a lens does not suffer any deviation. It is also referred to as optic cent..

We come across in our day-to-day life different forms of energy, like the mechanical energy, heat energy, electrical energy, chemical energy etc. Here in this chapter, we are mainly concerned with mechanical energy. The two types of mechanical energy are kinetic energy and potential energ..

The number of protons or the number of electrons in an atom in its normal state is called the atomic number and is denoted by Z. The nucleus of every element contains Z protons and some number of neutrons. The electrons, having the same charge as a proton but of opposite sign, nullify the charge of..

First law states that the mass of a substance deposited or liberated on an electrode during electrolysis is proportional to the total quantity of electric charge passed through the electrolyte. Second law states that if same quantity of charge is passed through several electrolytes, the mass o..

Batteries produce electricity by converting chemical energy into electrical energy. Batteries provide electricity to torches, transistors, toys, clocks and watch..

Sunlight falling on the earth's surface equals 50,000 times the energy used each year by man. Almost all our energy comes from sun. The sun's nuclear energy is responsible for the tidal energy, heat energy stored in water, the chemical energy stored in plants, and the kinetic energy store..
