Physics / Spherical Mirrors The branch of physics dealing with the properties and behavior of light is called optics. Light is a form of energy which helps us to see the objects. Have you...
Definition of Polarization As we discusses in previous atoms, light waves are a type of electromagnetic waves, in the visible spectrum. These electromagnetic (EM) waves...
In 1801 Thomas Young was able to offer some very strong evidence to support the wave model of light. He placed a screen that had two slits cut into it in front of...
الفلاش Work Done by a Gas When a gas expands it does work on its surroundings. That work is equal to the area under the curve on a P-V diagram which describehs that expansion....
Entropy A measure of the level of disorder of a system is entropy, represented by S. Although it"s difficult to measure the total entropy of a system, it"s generally fairly...
The first law of thermodynamics Thermodynamics Thermodynamics is the study of systems involving energy in the form of heat and work. A good example of a thermodynamic system is gas...
A diode is a very simple device and it has a lot of applications. We will cover some of its uses and explain exactly how it works in very simple terms. If you don"t...
What is an electromagnet? An electromagnet is a magnet that runs on electricity. Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of...
Capacitors are widely used in electronic circuits. Capacitors have vast applications. They are used in almost every Machine that is working with some electronics components.Now before reading or...
Although Einstein presented his photon model for the photoelectric effect in 1905, it was not until 1923 that the photon concept began to achieve widespread acceptance. It was then that the...
Calorimetry Heat Capacity Concepts When heat is transferred to an object, the temperature of the object increases. When heat is removed from an object, the temperature of the object decreases....
