Introduction Whenever a magnet is kept in a magnetic field it suffers force. A magnetic field is a physical field to describe the effect on magnetic materials. The uniformity of the magnetic field has a particular effect on the dipoles in its vicinity. It is very important to learn about ... Read More

Introduction Astrophysics is the branch of science that gives all information about the universe and our place. The surrounding that covers the total universe is called space. The universe contains all planets, stars, galaxies, and various forms of energy in the universe. Some of them have their illumination among the ... Read More

Introduction Every matter in the universe is composed of tiny particles called molecules. They attract each other with some attractive force. There exists an intermolecular force of attraction between molecules. The matter is classified into five categories based on the force of attraction between the molecules. They are solid, liquid, ...

Introduction Waves of all types suffer an interesting phenomenon as the speed of their source is varied. You have likely encountered this phenomenon in your own life. Recall what happens to the sound of a train’s horn as it passes by you at very high speed. This is an example ... Read More

Introduction Dimensions, in very simple words, are to study the nature of any object mathematically. To check how tall a person is, or to see how big the circle is, we have been using dimensions with the magnitude of course for quantifying the objects around us in dayto- day life. ... Read More

Introduction Optical instruments are devices that are used for the enhancement of the images of the object. Anything as simple as a magnifying glass fitted with a convex lens is also an optical instrument. These days we have even complex combinations of lenses that use a very basic phenomenon of ...

Introduction Thermodynamics is a study that establishes a relationship between heat and work. To understand it well, the concept of two terms- entropy and enthalpy has to be deeply dug in. In this article, the basic definitions of entropy and enthalpy, as well as the differences will be discussed in ... Read More

Introduction The phenomenon of separation of colors in white light is called dispersion. The collection of these colors is called a spectrum. A good example of a color spectrum is the rainbow. Rainbows occur when sunlight is refracted by water droplets during the rainy season. We can see a rainbow ... Read More

Introduction With help of our Eyes, we can see the beautiful world around us. This happens due to the light rays. The light rays fall on any object and get reflected by it. These reflected rays fall on our eyes. The eyes have many parts like cornea, aqueous humor, and ... Read More
