The prime objective of this post is to get familiar with bipolar junction transistor (BJT) and its related terminology. The primary purpose of a BJT is to amplify the current. This allows BJTs to be utilized as amplifiers or switches in electronic devices such as cell phones, industrial control, television,
Instructions on using the complex number calculator This complex number calculator dynamically calculates the operations that are needed to be done on given complex numbers. The calculated values are rounded off to 4 decimal places for accuracy. For single complex number, the given inputs are real part of a complex
Introduction to Electromagnetic waves and electromagnetic spectrum Waves are categorized into three main types, mechanical , electromagnetic , and matter waves. The waves that can pass through a medium are called mechanical waves. Whereas, electromagnetic waves (EM Waves), a special type of wave, do not require a medium to travel
A mirror is a reflecting surface that reflects light excellently and does not allow it to refract, producing a clear image. It produces either real or virtual images. A famous German chemist Justus made mirrors commercially available in 1835. He made the mirror by coating a thin layer of silver
Related Terms of Lenses Before discussing lens and their properties and application, one should be familiar with these terms. Refractive Index Refractive index is a ratio of the speed of light when it passes through the vacuum to its values when it passes through a specific medium. where c is
The human brain and the human eye cooperatively translate light into color. Light receptors are present in the eye, which transmits the messages to the brain. These light receptors are present within the human eye to produce the confidential sensation of colors. Newton perceives that color is not inherent in
About Sir Isaac Newton Sir Isaac Newton was an English mathematician and one of the most recognized and influential scientists in history. Newton is famous for providing laws of motion and gravity amongst his numerous works. He provided three laws of motion which are described independently below with a description.
Our discussion will start by explaining what is Kinematics? Kinematics is a branch of physics that Kinematics To explain the motion of an object, we first need to understand the branch of science that deals with the study of motion. The branch of the fundamental science of physics that deals
Chirality, as explained previously, is the inability of material or geometry to be superimposed on its mirror image. Chiral metamaterials are metamaterials with chiral geometry or arrangement. Due to their arrangement, they present different responses for different wave polarizations. A chiral metamaterial may provide a difference in transmission or reflection
Chirality is the object’s inability to be superimposed on its mirror image and therefore, chiral objects are not superimposable on their mirror image. On the other hand, achiral objects are those objects that “are” superimposable on their mirror images. These concepts of chiral and achiral objects can be better understood
