Introduction Energies that are found in nature can be classified into two sections, renewable and non-renewable energies. Out of these two, the renewable energy is produced over time and through natural processes. Renewable energies are capable of being constantly replenished over time. Renewable energy can be obtained from the three major sources present in nature that is, through the air, water and sunlight. The rural regions get highly benefitted from the renewable energy power plants. Renewable energies are highly useful in the long process of sustenance. What is meant by renewable energy? Renewable energy source is found all over ... Read More

Introduction Remote Sensing is one of the scientific methods that help to detect the physical properties of an area. This process is done without having any physical contact with the targeted objects. This process is mainly used for gathering information about different solar planets and Earth. Different types of fields like geology, ecology, meteorology, hydrology, geography, and glaciology used the method of Remote Sensing. Many other fields like military, planning, economics, and intelligence also used this method of sensing. Definition of Remote Sensing Remote Sensing technology is mainly used for gathering information on the Earth's surface without making ... Read More

Introduction Relativity is a notion that gives a statement that physics are the same everywhere. This theory is mainly related to time, space, and their relativity. Relativity is mainly defined that it is a state or quality of being relative. Relativity is a state of being dependent on the purpose of existence. This theory is related to gravity and the name of this theory mainly comes from the relativity of motion. What is Relativity? It is a theory proposed by Einstein that describes the dependence of different physical phenomena on the observer’s relative motion. The observer reflects the behaviours ... Read More

Introduction Relative speed is calculated by assessing the difference between two moving things that are travelling in the same direction. When moving things travel in the opposite direction, the speed of both the objects is calculated to compute the relative speed of the objects that are moving in different directions. What is Relative Speed? The idea of relative speed is applied when two or more bodies (objects) travel at a certain speed in the same or different directions. Therefore, relative speed can be defined as a concept that calculates the speed of one moving body concerning another body, travelling at ... Read More

Introduction Cloud formation in physics refers to the processes that create clouds in the atmosphere of planets, dwarf planets, moons, and other celestial bodies with atmospheres. We classified this process into two ways: those that make homogeneous clouds, like the cumulus clouds we are most familiar with, and those that make heterogeneous clouds, which have different characteristics from homogeneous clouds and often make up stratocumulus clouds and cirrus (or cirrostratus) cloud types. Overview of Cloud Formation Images Coming soon Clouds are formed when there is a difference in temperature between two layers of air. This causes rising motion, which leads ... Read More

Introduction: Coherent Sources of Light Light sources which produce light waves with the same frequency, constant or zero phases difference, and same wavelength are called coherent sources of light. Two coherent light waves make a sustained interference pattern. Both coherent waves make fixed maxima and minima overtime when they overlap with each other. Images Coming soon Here you can see this visual to understand coherent sources. You can read interference and parameters of light to understand this concept elaborately. Examples of Coherent Sources of Light Read the following example to understand coherent sources of light: The ... Read More

Introduction To have a deep understanding of the working of electric batteries, you need to have a basic knowledge of the properties of the materials that go into it, i.e., cells and electrolytes. Energy conversion and storage devices are the most powerful and vital of all devices used in electrical engineering and electronics applications. Although their uses can vary greatly, they typically convert one form of energy into another or store energy that can be retrieved later to perform work. What are Cells? Images Coming soon All of us have either used or have come across cells on a day-to-day ... Read More

Introduction In 1948, two scientists named Casimir and Polder made the following observation: If two uncharged, perfectly conducting plates are placed very close together, they will experience a small attractive force between them. This force became known as the Casimir effect or Casimir force, and it was one of the first demonstrations of zero-point energy ever recorded. The Casimir Effect The most common explanation for the Casimir effect is to say that quantum fluctuations cause energy density fluctuations in an otherwise flat space-time, which causes attraction between particles. But if you think about those kinds of fluctuations, they’re so minuscule ... Read More

Introduction The first law of thermodynamics states that in all closed systems, the total energy of the system is constant—it cannot be created or destroyed. This means that it’s impossible to make heat without also making work, and vice versa. The second law states that the entropy of an isolated system can never decrease, but must increase over time as it approaches equilibrium with its surroundings. However, there are ways to optimize thermal efficiency—one of these is Carnot’s theorem. Overview of Carnot's Theorem In a thermodynamic system, heat cannot be converted completely into work. This is due to a concept ... Read More

Introduction Bulk modulus is one of the most important properties in all of materials science. It’s defined as the ratio of stress to strain within a material and can be used to calculate things like how much stress it takes to fracture the material or how much strain it will undergo when you apply a given amount of force to it. If you’re working with any type of elastic object in your day-to-day life, then you’ll definitely want to brush up on this important material property. Bulk Modulus of Elasticity Before I go into detail on what bulk modulus of ... Read More
