Reading meter Rule with accuracy
A ruler is a tool mostly used to measure small lengths. A metre rule has a length of one metre, which is equal to one hundred centimeters. A ruler, also known as a rule, scale and sometimes a line gauge, is an instrument used to measure lengths. A user estimates a given length by reading…

Measuring Lengths: Creative estimation of a tree height-1
Measuring Lengths involves measuring distance between two fixed points. length is a one dimension quantity. The SI unit for length is the meter (m).Other units of length are indicated in the table below. UNIT SYMBOL EQUIVALENCE IN METERS Kilometer Km 1000 Hectometer Hm 100 Decameter Dm 10 decimeter dm 0.1 centimeter cm 0.01 millimeter mm…

Energy of Radiation
For a given metal surface, the kinetic energy gained depends on the excess energy of the radiation. This happens after the electron has been extracted to the surface.

The Quantum Theory
The quantum theory of light proposes that light travels in bundles of energy, known as a photon. In 1909, Max Plank proposed that light energy is propagated as a small packets of energy that are discrete. Each packet of energy is referred to as a quantum of energy. The discrete amount of energy are called photons…

Introduction to Photo Electric Effect
Photo electric effect is where we study behavior of metals when electromagnetic radiations falls on them. When metals are provided with some energy, electrons in their atoms are extracted and comes to the surface.

Introduction to heat conduction
Heat conduction is a process by which heat moves in solids by means of vibrations of it’s molecules. If you put one end of iron on fire, soon the other end will be hot, sometimes too hot to handle. The heat energy entering the iron from the hot end increases the vibrations of atoms. Atoms…

The law of charges
The basic law of charges states that like charges repel, unlike charges attract. In this lesson, we will discuss physics experiments that can verify this basic law. Experiments to verify the law of charges To investigate what happens when two charges bodies are brought together, you may need the following apparatus: glass rods silk cloth…

Electrostatics 1
Electrostatics is a branch of physics that deals with behavior and properties of charges that are not flowing. When materials are subjected to mechanical friction force against other materials, the electrons near the surface jump out from one material and become logded to the other material. In other word, when materials rub each other, electrons are…

Lines of Longitudes
lines of longitudes measures the distance east or west of the central line that divides the earth into two parts . This line is known as the Greenwich Meridian which passes through a city called Greenwich, England.
