A lens is a piece of polished glass with curved sides for concentrating or dispersing the beam of light rays. A lens is used for magnifying or reducing the image placed in front of it. Scientists use lenses for examining mirror-sized objects. People wear spectacles. The glass used in it is a good example of a lens. There are two types of lenses: concave lens and convex lens. The lens which is thicker at the end than the middle is called the concave lens. The lens which is thicker in the middle than the end is called a convex lens....
Inductance is a term that every physics student should be familiar with. It has its own formula and is frequently combined with resistance and capacitance. Oliver Heaviside first coined the phrase in 1886. In addition, we use the L to represent inductors on circuit diagrams and inductance in equations, in honor of the eminent physicist Heinrich Let’s learn about the Inductance formula and how to use it to determine the inductance of any item....
Reflection of light is a very important concept in physics. After all, this phenomenon is what allows us to see the world around us. In this article, the reflection of light is discussed....
The RC/IC circuit frequency variation is defined as the frequency of signals that can flow through the circuit. It is also known as the characteristic frequency. An RC circuit is one that has a resistor and a capacitor connected in series. It suppresses frequencies less than f while allowing signals with frequencies greater than f to flow freely. However, signals with frequencies close to f are nonetheless partially transferred. Depending on the design, the RC filter can be used to filter out low or high frequencies. An integrated circuit (IC) is a semiconductor that contains hundreds of millions of small capacitors, resistors, and transistors....
In shaded locations, the heat index is a temperature that combines air temperature and relative humidity. Perspiration or sweating is a natural way for the human body to cool down. Sweat evaporation is responsible for removing heat from the body. High relative humidity, on the other hand, slows evaporation. When the temperature is 32 degrees Celsius and the relative humidity is 70%, the heat index number equals the actual air temperature....
Average Speed is defined as the mean speed of any object observed over a period of time. The average Speed Formula is the formula used to find an object’s average speed throughout the journey which is completed over a duration of time. Suppose a car travels from point A to b and in t hours and comes back in T hours then the average speed of both the journey is the total distance covered by the car divided by the total time taken by it. Thus, the average speed formula is the total distance dived by the total time taken by an object....
The largest deviation of a variable from its mean value is referred to as amplitude. It is the largest displacement from a particle’s mean location in to and fro motion around a mean position. Periodic pressure variations, periodic current or voltage variations, periodic variations in electric or magnetic fields, and so on all have amplitudes....
The heat load is the amount of heat energy that is expected to be injected into a specific space in order to keep the temperature within an acceptable range. The heat load is equal to the product of mass flow rate, specific heat constant and change in temperature. It is denoted by the symbol Q. Its standard unit of measurement is watt (W). Its dimensional formula is given by [M1L2T-3]. It has two categories, internal heat load and external load. The former works on a conditional area while the latter is based on the heat supplied to the air after it exits a location....
Force is pushing or pulling any item coming about because of the object’s connection with another object. Without force, nothing can be moved, halted, or shift the course. It is a quantitative communication between two actual bodies, between an article and its current circumstance. There are different sorts of powers in nature. Assuming an object is in its movement state then its present status will be either static or movement. Its position might be changed assuming it is pushed or pulled. The outside push or pull applied on the object changes its present status of movement is known as Force. This power can be of various sorts....
Equations of Motion was given by Sir Issac Newton; who is considered the father of mechanics. He was the first to give the fundamental physical laws that deal with objects and their motion. He formulated three equations of motion of an object and published them in his book Philosophiae Naturalis Principia Mathematica, which is considered the starting point in the history of classical mechanics....
According to the theory of relativity, time dilation is defined as the difference between the elapsed time of two occurrences assessed by either moving relative to each other or by gravitational mass or masses located at different locations....
Force is just defined as a push or pull of an object with the mass that causes it to change its velocity. It is an external agent that is capable of changing the state of a particular body neither in a rest position nor in motion. It has both magnitude and direction. It can be measured using a spring balance. The formula of force is F = ma, where m = mass of the object, a = acceleration....
