Alternating Current and Direct Current are the configurations to provide direction to the current flow. Alternating Current (AC) vs. Direct Current (DC) comparison shows a huge difference between the two ways of current flow. DC is taken as the setup … Read more
In electricity, current can be made to flow in two ways: either uniformly or periodically back and forth. Direct current (DC) is a type of electric current where the electric charges always move in a uniform direction, thus producing steady … Read more
Definition of Alternating Current (AC) We know in DC circuits, the current is made to flow in a uniform direction. However, electric charge can also flow periodically in reverse direction. This flow of current is known as Alternating Current; The … Read more
Definition of Near Point (Least Distance of Distinct Vision) Human beings or any other living organisms have their unique vision characteristics. A human eye can only see an object sharply and clearly to a certain extent without creating any strain … Read more
Definition of a Lens in Optics A lens is a transparent, optical device that stays on the laws of refraction and is used for multipurpose in physics and engineering. Being made up of plastic or glass they are also slightly … Read more
Definition of Dispersion of Light A white light gets amazingly separated into different colors when it strikes a special medium like glass prisms. This phenomenon of light is known as the dispersion of light. Main reason for this to happen … Read more
What is a Diamond? A diamond is a precious gem that occurs naturally. It is a cubic lattice composed of carbon atoms. naturally. Deep inside the earth where temperature and pressure are high enough are the more likely areas containing … Read more
Definition of a Mirage A mirage is an optical illusion caused by the bending or refraction of light. As it passes through layers of air of varying temperatures the deviation in the light path occurs. The deviation gets so strong … Read more
Definition of Total Internal Reflection Total Internal Reflection (TIR) is also one of the phenomena of refraction which sends the incoming rays of light passing from one medium to another again back to the initial medium. It is a condition … Read more
