Free Vibrations: If a given body is once set into vibrations and then let free to vibrate with its own natural frequency, the vibrations are said to be free vibrations. The natural frequency of free vibrations depends on the nature and structure of the body and in ideal situation, the amplitude, frequency and the energy Read more about Free, Forced, Damped and Resonant Vibrations[…]
Hello MyRankers, here is the explanation of YOUNG DOUBLE SLIT EXPERIMENT 1. In Young’s double slit experiment, if monochromatic light is replaced by white light then central fringe will be white; all other fringes will be coloured. White light consists of colours between violet and red (VIBGYOR). Wavelength λ is the shortest for violet light and Read more about YOUNG DOUBLE SLIT EXPERIMENT[…]
Characteristics of EM waves: 1. Electromagnetic waves are transverse in nature. They are produced by varying electric and magnetic fields. In an electromagnetic wave, the electric and magnetic fields oscillate perpendicular to each other as well as perpendicular to the direction of propagation of the wave. Both electric and magnetic fields vary in phase with Read more about Hello MyRankers, here is the explanation of EM waves characteristics…….[…]
Any guesses which topic in physics, forms a highly weighted section and major part for IIT-JEE..?? Its “ELECTROMAGNETISM”, which requires a lot of practice, understanding and skills to apply and solve the problems. To conquer this topic, the applications learnt in mechanics is going to help especially in the solving process. The chapter wise analysis Read more about What to focus in ELECTROMAGNETISM…?[…]
Ever thought of How can a plane fly? In a storm how does a house lose its roof? Why do rabbits not suffocate in the burrows? Why does a cricket ball swing or a baseball curve? Here the answer is given by the Bernoulli’s principle!Bernoulli’s Equation: Let us focus our attention on the motion of Read more about Bernoulli’s Theorem….[…]
As we all are aware of how important mechanics is in physics, here are more tips to solve problems further. Though intensive practice is required in mechanics, it is essential to know how to solve the problems too…. Here are few ways to approach problems in mechanics… In a PLANE: 1. Problems where there is Read more about How to solve problems in mechanics…??[…]
Here is a brief explanation to know about the distribution of current and voltage in series and parallel connections. Distribution of current in parallel connection: When all the devices are connected using parallel connections, the circuit is referred to as a parallel circuit. In a parallel circuit, each device is placed in its own separate branch. The presence Read more about Distribution of current and voltage in parallel and series[…]
In classical mechanics, a constraint is a relation between coordinates and momenta (and possibly higher derivatives of the coordinates). In other words, a constraint is a restriction on the freedom of movement of a system of particles. The only difference between a constraint equation and eg a conservation equation is that a conservation equation is physics, but Read more about Constraint Relations[…]
L-R Series circuit (inductor in series with resistor): A resistor-inductor circuit (RL circuit) is an electric circuit composed of resistors and inductors driven by a voltage or current source. A first order RL circuit is composed of one resistor and one inductor and is the simplest type of RL circuit.Using Kirchhoff’s voltage law According to the law, the Read more about LR and RC circuits[…]
