What is Resonance?

Definition: Resonance occurs when the frequency of the applied periodic forced is equal to one of the natural frequencies of vibration of the forced or driven harmonic oscillator. Explanation: Associated with the motion of a driven harmonic oscillator, there is a very striking phenomenon, known as resonance.It arises if the external driving force is periodic […]

Computer languages

What are computer languages?

As we all know human languages are known as natural languages. Unfortunately, computers can not understand natural languages, as a result we have to communicate with computers using computer languages. These languages are: High level languages Low level languages Assembly languages Machine Languages The architecture of computer languages is given below. High level languages: HLL is […]


What is Spectrometer?

A spectrometer is an optical device used to study spectra from different sources of light. With the help of a spectrometer, the deviation of light by a glass prism and the refractive index of the material of the prism can be measured quite accurately. Using a diffraction grating, the spectrometer can be employed to measure […]


Combustion Analysis

Definition: The analysis which is made to determine the amounts of different elements present in a compound by burning a known amount of organic compound containing C, H and O in the presence of oxygen is called” combustion analysis.” Procedure: A weighed sample of the organic compound is placed in the combustion tube. This combustion […]

Google Project Soli

About Soli: Project Soli is Google ATAP’s attempt to get rid of external input devices and make use of the human body as the only input device. As devices get smaller, interacting with them via a display become difficult. Project Soli makes use of your hand and finger movments to interact with wearables or devices […]

Newton’s Third Law of Motion

Definition: “To every action there is an equal and opposite reaction.” OR “When two bodies exert mutual forces on one another, the two forces are always equal in magnitude and opposite in direction.” Mathematically we can write; FAB = – FBA it is important to remember that the action and reaction forces always act on […]

Newton’s Second Law of Motion

Definition: “If a net force acts on a body the body accelerates. The direction of acceleration is the same as the direction of net force. The magnitude of acceleration is in inversely proportional to the mass of the body.” Mathematical: [latex s=2]a\propto F[/latex] [latex s=2]a\propto \frac{1}{m}[/latex] Combining [latex s=1]F = K ma[/latex] where k=1 [latex s=1]F […]

Newton’s First Law of Motion

DEFINITION: “In the absence of unbalanced force (net forces), a body at rest will remain at rest and a body in uniform motion will remain in uniform motion in a straight line.” EXPLANATION: Experiments shows that when no not force acts on a body the body either remain at rest or moves with uniform velocity […]
