Introduction A two-stroke engine is associated with the kind of engine that utilizes internal combustion to generate a complete power cycle. The two-stroke engine completes a power cycle utilizing two strokes of the piston. Furthermore, this power cycle is completed in a single revolution of the crankshaft. These engines have a distinct property of retaining a high power-to-weight ratio and the power is available within a very shallow range of rotational speeds which are referred to as the power band. What is a two-stroke engine? Aa (2020), the two-stroke engines work on a very specific principle that the starting ... Read More

Introduction The transistor refers to simple components that are mostly used to build different types of electrical devices and different projects. It is an electronic device that is mostly applicable in the electric circuit to amplify the electrical signals as well as allows it as a wide array of electrical devices. The transistor is classified into three different categories like emitter, base, as well as collector. The principal idea that is behind the construction as well as the working principles of the transistor is based on the current flow to the electric circuit. What is a transistor? The characteristics ... Read More

Introduction The lens maker’s formula is utilized by the lens manufacturers and is used to make lenses of a certain extent of power from a glass of distinct refractive index. It helps the lens makers to derive the necessary data about the curvature that is required to manufacture a lens of a particular focal length in association with the material of a certain refractive index. This formula uses multiple sign conventions which are crucial to set up various geometric relations. This formula is used in the cases of concave and convex lenses alike. What is the Lens maker’s Formula? ... Read More

Introduction Friction is very helpful in several cases as it offers a great quantity of measure to an object's motion. For example, when a ball has thrown on the floor then it began to move with a few velocities. As per the first law of Newton the direction, of the motion direction determines the friction of the object. More than 20% of the engine or battery power of different automobiles is mainly consumed by overcoming the frictional forces of the different mechanical parts. What is friction? Figure 1: Friction of the rough surface ... Read More

Introduction Fossils can be described as impressions, traces, or remnants of any organisms that used to exist in past geologic ages and have got preserved in the earth crust for several years. Trails, tracks, and imprints can also get fossilized just like worm burrows and dinosaur footprints. Imprints, trails, and tracks are referee to as the traced fossils. There are various types of fossils that are found on the earth such as: Petrified Fossils, Molds and Casts fossils, Carbon Films fossils, Trace Fossils, Impression fossils, Compression fossils and Pseudo fossils. The fossils are formed when the animal or plant ... Read More

Introduction Force mainly defines the pulling or pushing of an object and force is the most important part of the movement of objects. It can also be called the quantitative interaction between two physical bodies. The two bodies here are the environment and the object. Different types of forces can be seen in this part and among them Contact forces and Non-Contact forces are the most important. In this part Non-Contact forces is classified into three parts- Nuclear Force, Gravitational Force, and Electromagnetic Force. The Contact forces also have many variations like- Tension Force, Air Resistance Force, Frictional ... Read More

Introduction Energy is abundant in nature and it exists in multitudes of forms that can transform from one form of energy into another. These energies are mainly classified into potential and kinetic energy these energies can however be sub-divided into various other categories that have their own set of distinct functionalities and principles. These energies however can be subdivided into various other forms like gravitational energy, atomic energy and many more. The kinetic energy is the kind of energy that is mostly available in the moving objects. The potential energy is classified into the form of ... Read More

Introduction The transistor is the kind of service that works in an active region, the transistor acts as an amplifier and in case it acts as a switch it tends to perform in various cutoff and saturation regions. In the transistor that is working in the cutoff state, both the collector base and the emitter-base junctions are reverse biased. The transistor can act as a device, switch and amplifier. All these aspects accumulate to provide a service in multiple regions for example transistor as an amplifier is useful in the functionality of the optic fibers and is also useful ... Read More

Introduction Identifying the path of the white light through a triangular prism is an important scientific experiment. It is used to exhibit the spectrum of visible light. Different types of light hold different colors when they pass through a triangular prism they are divided into multiple spectra and thus by this experiment is found that a mere white light possesses the different colors in it. This experiment was first done by Isaac Newton in 1665. Some significant facts of Triangular Prism Triangular prism is generally a polyhedron that has two parallel bases. When a particular ray of light divided into ... Read More

Introduction The nature of a light’s path-changing process is evaluated based on the experiment in which the path of light is traced when it crosses a glass slab. According to Snell’s law of refraction, the nature of light varies from its traveling medium. Interpreting the result helps an individual to understand the reason behind changes in the value of refraction. Figure 1: Light passing through a glass slab Aims The aim of this experiment is to trace the exact path in which light passes if it has to pass through a rectangular glass slab. Another aim of this experiment ... Read More
