You might have heard about Optical Fibers, which are pliant, ductile, and crystal clear. These are made by drawing silica or plastic and are slightly thicker than a human hair. Metal fibers are preferably used for transmission in optical fiber commun

Laws of motion were firstly introduced by Issac Newton. He stated three laws which nowadays are known as Newton’s law of motion. His first law was the ‘Law of Inertia’, the second law of motion was F = ma, and the third law of motion was the law of a

The pitch of a sound is our ear's response to the frequency of sound. Whereas loudness depends on the energy of the wave. The pitch of a sound depends on the frequency while the loudness of a sound depends on the amplitude of sound waves. Normal huma

It has been a passion of mine to study science my entire life. In the past, its significance has been immense. Students in our schools have had science taught and have been exposed to the fascination of this subject throughout the year. As science ha

Science has always been a thing of deep interest and has been a tithing of great interest. We all even in our schools have witnessed how science has been a thing of interest and an amazing subject. In science, we all have encountered one of the best

No doubt that advancements in technology have taken our lives to a whole new level and we all can see how amazingly we all are relying on the same. In the same way, we all can think about the best of all concepts which are very basic ones too like ma

Science has definitely taken some drastic advancements and made all of us somewhat dependent on these innovations. There are several concepts of science that have made our lives a little bit easier and interesting. Yes, we are talking about those phy

Ocean acoustics is the screening of sound changes and their character in the ocean. Sound-pressure waves are formed by vibrating underwater objects, which in turn compress water molecules. And sound waves travel through the ocean. Sound waves emanat

The electrochemical cell has a major role in our daily lives, An electrochemical cell is a device that converts stored chemical energy into electrical potential energy. It has two terminals, made of metal: one terminal is positive, while the other is

According to physics, conductors are materials that allow the flow of charge in one or more directions. Conductors allow charge transfer through the free movement of electrons. Unlike conductors, insulators are materials that impede the free flow of

Lenses are mainly used to make images of an object view, the word lens is derived from a lentil bean from the Latin language, most lenses are spherical lenses, their two surfaces are parts of spherical surfaces. In general, there are two types of sph

We observe the magnetic effect of electric current, when a compass is brought near the conductor, the needle of the compass is deflected due to the flow of electricity. This shows that electric current creates a magnetic effect, this effect of electr

We extensively use the heating effect of electric current in our daily lives. Traditional methods of cooking and washing using electric iron, kettle, toaster, heater, etc. all of these reflect the heating effect of electric current. Definition of hea

Without light, the life of any creature is not possible on earth because light plays an important role in our life. Without light the earth is incomplete, the whole world is black and all things are black. Light helps us to see, recognize, and unders

Quantum entanglement is a physical incidence, an incidence that occurs when a pair of particles or groups of particles are produced or mingled in such away. The quantum state of each particle cannot be independently described as the state of the othe

Time and distance are important and unavoidable topics for all competitive exams. Speed = distance/time,Time = distance/speed,Time = distance/speed X km/h = (x × 5/18) m/sec X m/s = (x × 18/5) km/hr Suppose a man covers a certain distance at x k

The speed of sound varies in different mediums and the speed of sound in a medium depends mainly on the elasticity and density of the medium. The speed of sound is most commonly in solid, then in liquid and then in gas. The speed of sound in a medium

Physics is a branch of science which deals with the structure of matter and the interactions between the basic constituents of the universe. The main goal of physics is to understand the behavior of the universe. So take this quiz and know more about

The electric potential is called the amount of work that has to be done to bring a unit's positive charge from infinity to a point. In other words, the electrical potential energy stored in a positive point positive unit at a point is equal to and eq

A transformer is an electrical machine used to change the voltage of an alternating current that has the same frequency. Which is used to convert the voltage of the alternating current to the same frequency, that is, the transformer with low voltage

An Electric Motor is a device that converts electrical energy into mechanical energy, as you have always seen that we supply electrical energy to the motor and we get rotating energy that we are mechanical energy. Power is an ideal staple driver in t

The fundamental particle of photon radiation is spoken whose mass is zero. Photons, like all fundamental particles, show wave-particle contours, that is, they have the tendency of both wave and particle. The modern form of photons was given by "Alber

An elementary particle may belong to one of two groups, which are the building blocks of the ferryman or boson's fermions matter, and are mass, while bosons behave as force carriers for Permian interactions and some of them have some Is not a mass. T

Light is a form of electromagnetic radiation with a wavelength that can be detected by the human eye and it is also a form of energy. This type of energy is called radiation. All sources of light produce radiant energy. We cannot see the radiant ene

The electromagnetic spectrum is distributing electromagnetic radiations based on their frequency or wavelength, known as the electromagnetic spectrum, that is, distributing electromagnetic radiations based on frequency or wavelength based on frequenc
