Introduction Vocal cord plays an essential role in the communication skill of human beings. The cord with the accommodation of noise, tongue, and mouth helps in creating sounds. The creation of sound is bliss for humans and they have gained the capacity of communicating with the gift of the vocal cord. It is called the source of the human voice and there are three main parts of voice production Vocal cord, source of Human Voice The skill of communication is the most important part of human life. The communication of humans has happened using the vocal cord. It ... Read More

Introduction The eye is one of the 5 sensory organs apart from the nose, ear, tongue and skin. It enables the power to see every object that is around us. In simple words, it works like a camera that captures visions. Eyes also catch the light rays from our surroundings and make them convert in a way that makes the further process in the brain and make humans see any object near or far. What is a human eye? The human eye is an organ that can transform electromagnetic waves into images in a long and complex process. ... Read More

Introduction The process of the heating effect of electric is attached to the daily human lives as most of the components used in daily activities are influenced by this phenomenon. Daily components like toaster, electric iron, heater and electric kettle are deeply moved by this process which makes it a significant part of the daily human lives. When a flow of current passes through a conductor it generates head as the hindrance is higher within the conductor this process influences the heating effect of eclectic in real-time. Discussion on the heating effect of current The heating effect of ... Read More

Introduction It is often that we wonder how it is possible for any mass to deny the gravitational pull of the earth. The mass of the earth is $\mathrm{5.972\:\times\:10^24\:kg}$ is quite heavy and based on its mass, its pull will be much stronger in nature. This leads to the question of its possibilities and that provides the answer that the rockets induce the principle of huge velocities that are better known to be escape velocities. With this force exerted, the rockets are able to suppress the high gravitational pull of the earth and travel to outer space. What are ... Read More

Introduction In accordance with the discoveries of physics, all the aspects that have electromagnetic radiation are generally known by the name of light. However, the human eye can detect only a small section of this electromagnetic spectrum. The human eye consists of cone-shaped cells those are responsible for making this electromagnetic spectrum visible to the eye. Based on such conceptualisation of physics, the present tutorial will include an explanation of the visible light spectrum. What is the visible spectrum of light? Figure 1: Visible light spectrum The visible part of the electromagnetic spectrum to a human eye is referred ... Read More

Introduction “Ultraviolet rays” (UV rays) are the portion of the Electromagnetic Spectrum varying from the ending of the visual light coverage to the X-ray area. These rays are harmful to the human skin and eyesight. Continued consumption of “ultraviolet rays” can cause several disorders. Additionally, the “ozone layers” consumed a large number of “UV rays” that come from the sunlight. Moreover, “mercury lamps, black lights, and tanning lights” are several sources of the UV rays present in the atmosphere. About the Electromagnetic Spectrum The “Electromagnetic (EM) Spectrum” is the field of all classified radiations. “EM radiation” comes from different ... Read More

Introduction The electromagnetic spectrum refers to a range of all frequencies f electromagnetic radiation that includes invisible radiation as well s visible lights like the radio waves, gamma rays and infrared waves. The electromagnetic radiation from spectrum has multiple uses in the manufacturing and communication field. Gamma rays generally refer to the high frequency electromagnetic radiations and these rays carry enormous energy. Gamma rays can pass through from all types of materials. There are a few exceptions like thick concrete and lead bloc through which these rays cannot pass. Electromagnetic spectrum and gamma rays Gamma rays consist of ... Read More

Introduction Direct current sources are important as it provides power to an electric motor. According to Faraday’s Law, the interaction between the electric current and magnetic field helps in generating a force. This generation is done in form of a torque that is applied and used in a motor’s shaft. Some of the most important examples of direct current sources are rectifiers and batteries. Even alternating some current sources like a power grid, inverters and electric generators can also be helpful in powering an electric motor. Parts of an electric motor Each electric motor is developed with some ... Read More

Introduction The idea of the electric generator was formulated far before the correlation between electricity as well as magnetism. This machinery particle is mainly operated by the electrostatic principles that guide to operate with the application of plates as well as moving belts. This particular form of generator is mainly used during the sudden current off and in other emergencies. In the current situation, the application of the electric generator is seen in every transportation vehicle like aircraft, ships, and trains. In the field of automobiles, the type of generator is also severally used The working principle of electric ... Read More

Introduction Electronic communication systems dissolve the communication power to both the positive and negative impacts. Analogue or digital signals are fed to the system, processed in the circuits electronically for transmission and then deduced by the receiver. Electronic communication systems are said to be highly reliable and efficient when the errors are minimised in the procedures. Social networking is the most utilised electronic communication system among the rest. People utilise mostly to share their opinion, and views on a respective matter through the assistance of social media platforms. What is an electronic communication system? Electronic communication is referred ... Read More
