Thermal Equilibrium
Definition: It is observed that if a body, hotter than the environment, is kept at open space, it loses heat until the temperatures of the…
Thermometric Substance
Definition: The branch of physics (or heat) relating to the measurement of the temperature of a body is called thermometry. A thermometer is an instrument…
The Laws of a Simple Pendulum
A simple pendulum has a small-diameter bob and a string that has a very small mass but is strong adequate not to stretch significantly. The…
Seconds Pendulum
Definition: If the time period of a pendulum is 2 seconds, it is called Seconds Pendulum. i.e. It is a pendulum which takes one second…
Simple Pendulum
Definition: A Simple Pendulum is defined as a heavy particle suspended by a weightless, in-extensible but perfectly flexible string. The point of suspension should be…
Oscillatory Motion
Definition: It is a kind of periodic motion in which an object reverses its direction after a certain interval of time. Any particle in periodic…
Periodic Motion
Definition: If the motion of a particle (or an object) is such that, it passes through a certain point from the same direction after a…
Wave Propagation in Dilute Plasmas
In this section we consider wave propagation in an ionised plasma comprising ne electrons and rti ions per unit volume. In a dilute plasma we…
Standing waves on Open Circuited Lossless Transmission Line
Unless the line is terminated with the characteristic impedance there will also be reflected waves traveling in the —x direction, and the wave amplitude will…
