No of lines of force perpendicularly passing through the given Area is known as flux. The total number of electric field lines passing a given... View Article
Magnetic flux is defined as the number of magnetic field lines passing through a given closed surface. It provides the measurement of the total... View Article
Here, the cause of the EMF is the motion of the rod to the right. The induced EMF establishes a current I in anticlockwise direction, so that the... View Article
According to lenz’s law, the induced EMF always opposed the cause which is producing it. If the cause of the induced EMF is a time varying... View Article
An isothermal process is a constant temperature process. Any heat flow into or out of the system must be slow enough to maintain thermal... View Article
Internal energy can be thought of as all the energy in a system that is not being transferred as heat. This could include nuclear energy,... View Article
States of a thermodynamic system can be changed by interacting with its surrounding through work and heat. When this change occurs in a system,... View Article
In the late 1800s, it was known that when a gas is excited using an electric discharge and the light emitted is viewed through a diffraction... View Article
When atoms are heated or subjected to an electric discharge, they absorb energy, which is subsequently emitted as radiation. Actually electrons... View Article
Like the Balmer series is the part of the hydrogen emission spectrum which is generated by the excitation of an electron from the second shell to... View Article
It was in 1885 when Balmer first of all came up with a simple formula for predicting the wavelength of any of the lines in what we now know as... View Article
When a hydrogen atom absorbs a photon, it causes the electron to experience a transition to a higher energy level, for example, n = 1, n = 2.... View Article
When Hydrogen gas is passed through a discharge tube (A hydrogen discharge tube is a slim tube containing hydrogen gas at low pressure with an... View Article
Hund's rule predicts the stable state of an atom to have large number of unpaired electrons (High spin configuration). The ground state is given... View Article
