Introduction Muscles are made up of elastic tissue. In the human body, more than six hundred muscles are present. Thousands of muscle fibers constitute elastic tissues. Muscle strength depends on the presence of fibers. These muscles work together with the nerve fibers to do all voluntary and involuntary functions of ... Read More

Introduction Proteins are very complex substances that are present in every living organism. Proteins have high nutritional values which play a direct role in the chemical process which is necessary for life. For example, muscles, for instance, contain about 30% protein, the liver 20 to 30%, and red blood cells ... Read More

Introduction Atoms are a basic unit of material. According to the Bohr atom model atoms contain a small central core called a nucleus which is full of positive charges. Electrons are round about the nucleus in a particular circle named orbits. The circular path is maintained by the centripetal ... Read More

Introduction You are use electronics in your daily life from every small object to a big machine. The device by which you are reading this article is also a part of electronics. Electronics is a vast field that contains a huge amount of components like conductors, switches, circuits, diodes, processors, ... Read More

Introduction We know that the structure of atoms is the same as the solar system. In the solar system, the sun is the center and other planets revolve around it in a definite path same as The atom nucleus at the center and electrons revolve around it. However, we found ... Read More

Introduction The release of electrons from a metal surface is known as electron emission. The nucleus is at the center of an atom, and electrons revolve around it. Electrons move in a variety of orbits. The electrons in the first orbit are strongly drawn to the nucleus. However, electrons in ... Read More

Introduction We see beautiful nature through light, which is an electromagnetic wave. We hear sweet melodies through sound waves. Waves have numerous applications in everyday life, from cellular communication to laser surgery. If we drop a stone on a steady surface of the water, we will see a reflection on ... Read More

Introduction Light travels across space and different media in the form of electromagnetic waves. The term electromagnetic means they contain both electric as well as magnetic fields. Akin to other waves, light waves are also characterized by a certain frequency and wavelength. For example, light waves with frequencies in the ... Read More

Introduction The electromagnetic spectrum encompasses a wide range of radiation emitted by stars, such as our sun. Waves of electromagnetic radiation commute through space. The frequency of a wavelength explains the no of waves/second it generates. Wavelength is the size of a wave in meters. At one end of the ... Read More

Introduction Before diving into microwaves, we must study a few basic concepts about the electromagnetic spectrum. As you might be aware, light behaves like a wave in certain situations. Not only that, but it is also an electromagnetic wave, which means it carries both electric as well as magnetic components. ... Read More
