Understanding Superconductors A superconductor is a material that, under specific conditions, displays four distinct changes indicating its transition to the superconducting state. (1) Electronic Effect:
What is Superconductivity? Zero Resistance: Superconductivity occurs when a material offers almost zero resistance to the flow of electric current, enabling energy-efficient electrical appliances and lossless
What is String Theory? String theory provides a theoretical framework in which all particles, from photons to quarks, are one-dimensional strings as opposed to zero-dimensional
Insulator and conductor are two different types of substances with different properties. Let us see how they differ from each other. What is a Conductor?
What is the Sand Battery System? The battery is a massive steel silo, 7 m tall and 4 m wide with 100 tonnes of sand,
There are three main types of nuclear radiation: alpha particles, beta particles, and gamma rays. 1. Alpha particles are made up of two protons and two neutrons
We often talk about heat and temperature in our day to day life while talking about the weather, hot metallic substance, tea, coffee, fever etc.
Introduction Generally, we see when we put iron nails at some distance to the magnet, it gets attracted towards it. Why is that so? We
In accordance with the universal law of gravitation, the terms gravity and gravitation define the circumstance that allows masses to be drawn together. Both names
What is a Diamond? The carbon allotrope known as diamond comprises sp3 hybridized carbon atoms and is exceedingly stable. The face-centered cubic crystal structure refers
Understanding the key difference between gas and vapour before using either word can help to reduce misunderstandings. The matter may be found in three different
A – Ampere, sometimes shortened to “amp,” the basic unit of electric current AC – Alternating Current (as opposed to direct current) or Air Conditioning (depends
Introduction Transistors, which are tiny electronic components, have two main uses. They can act as switches to control circuits and amplify signals. There is a
People keep many things in mind while building a house. The same goes with the government while building roads, tunnels, bridges, etc. The main aspect
Physics comprises of many vivid terms and topics like gravity, inertia, kaleidoscopic images, concave mirror, convex mirror, etc. But there is one topic that we
We have heard terms like inertia, gravity, concave mirror, convex mirror, etc., in our physics classes. Concave and convex mirror are broadly classified terms that
We know that LED and CFL bulbs are much better than the traditional incandescent ones but which is better out of the LED and CFL
Before moving on to the difference between Ac and Dc, let us quickly look at the current. Electric current is defined as the flow of
Physics is the study of the forces, the energy, and the matter that make up the Universe and everything in it. APPLIED PHYSICS uses the discoveries
Why is Graphene a Super material? Measuring in at just one atom thick, a sheet of graphene checks all the boxes of a super material:
Component Description Usage Resistor A resistor is a device which resists the flow of current in a circuit, thus reducing the voltage available to the
Images formed by Concave Mirror Position of object Position of image Nature of image At infinity At focus (F) Real, diminished, inverted Beyond centre of
Images formed by Convex Lens Position of object Position of image Nature of image At infinity At focus Real, diminished, inverted At 2F At 2F
Facts to Remember The speed of sound is 343 m/s The audible range of sound in human beings is 20 Hz to 20,000 Hz The
📕 परम ताप: परम ताप केल्विन तापक्रम पर आधारित है जिसके अनुसार दाब पर पानी का हिमांक 263∘K और क्थनांक 363∘K होता है | परम
Frozen water in the form of an icicle. Temperature is a key aspect of everyday human life; doctors use it to determine the health conditions
Water freezes at 0 degrees Celsius. The freezing point can be defined as the temperature at which a liquid transforms into a solid at a
Aluminium is a metal found in the second row and Group 13 on the periodic table. It is the third most abundant element after oxygen
Water boils are 100 degrees Celcius (212 Fahrenheit). The temperature at which substance change from liquid to the gaseous state is known as the boiling
Ice floats due its density, and because of the intricacies of buoyancy versus gravitational force. Water is a compound which exists in three forms: solid,
The units used to denote temperature include Celsius (Centigrade), Kelvin, and Fahrenheit. Celsius and Fahrenheit are units for measuring temperature used in contemporary society. Temperature
The starting points of Celsius (C) and Kelvin (K) are different. What is Temperature? Temperature is the intensity of hotness or coldness of an object.
A granular material is made up of solid macroscopic particles that interact with one another but lose energy while doing so. Granular materials are solids
If your thoughts tend to wander toward the grammatical, you’ve probably noticed that sound and noise are often used interchangeably. There doesn’t appear to be an obvious delineation between
To understand heat, we have to get down to the molecular level. Heat is energy. It’s caused by the movement of atoms. The faster an object’s atoms move, the hotter it
Have you ever played laser tag? If so, you know there’s nothing like it. Darting through the fog, dodging lasers as you aim for members
Did you know temperature can even change the speed of sound? It’s true! Are you WONDERing how? Let’s start by talking about what sound is. Sound
When you left, you had a tall glass of iced tea and an ice cream bar. Upon your return, you have a tepid glass of watery tea and a
What exactly is a kaleidoscope? They look a little bit like small telescopes you can hold in your hands. One end has a hole you
Have you ever seen a picture of a baby inside his or her mother’s body? If so, you may have wondered how doctors get their
The laws of physics show that every piece of glass — actually, every material on Earth — has a natural resonant frequency. That frequency is the speed at which it will
Basically, anything with a smooth surface that reflects almost all of the light that hits it — with only very little light absorbed or scattered
The matter is all around you. The matter is anything that has mass or takes up space. If it’s made up of atoms or molecules,
Work = force × distance कार्य = बल × दूरी 2. Energy = force × distance ऊर्जा = बल × दूरी 3. Speed = distance
Quantity – Units (S.I.) ●Length – Metre ●Time – Second ●Mass – Kilogram ●Area – Square meter ●Volume – Cubic meter ●Velocity – Metre/second ●Acceleration
Optical illusions are images or pictures that we perceive differently than they really are. Put another way, optical illusions occur when our eyes send information to our brains that tricks
3D stands for three-dimensional. “Regular” movies are 2D, or two-dimensional. What are dimensions, and what’s the difference? Dimensions are properties of space. They refer to extension in a particular
Can you feel the pressure? It’s around you…all the time…everywhere you go. What is it? Atmospheric pressure — often referred to simply as air pressure — is the constant force exerted on you
Mass measures the number of atoms in an object, combined with the density of those atoms. Mass is how much “stuff” is in an object. Mass isn’t the same as size,
When air particles vibrate, they bump into other particles near them. Then these particles begin to vibrate and bump into even more air particles. When
