Wave Motion
Here we’ll look for mechanical waves-transverse and longitudinal waves. In transverse wave particles oscillate in perpendicular to direction of wave propagation and in longitudinal they oscillate in parallel with wave...
ELECTROSTATICS
Electrostatics starts with the basic idea of charged particles and their properties. Know about simple experiments to demonstrate various things. Charged body can be made by charge induction or rubbing. Know about three basic...
SIMPLE HARMONIC MOTION
We know that oscillations are the motions which repeat themselves again and again. Simple harmonic motion is also type of oscillations which can be written as equation in form of sine or cosine form. They are also called...
MAGNETIC EFFECT OF CURRENT AND MAGNETISM
First of all magnetic field lines are produced from magnetic pole and ends on it. These lines form closed loop. Charge moving in magnetic field experiences force which is dependent of velocity of charged particle. Its direction...
PHYSICS OF NUCLEI
Here we’ll have a look on nucleus of atom. It is consisted of nucleons i.e. protons and neutrons. Before that you should know about atomic mass and its units which we study in chemistry. Atomic mass of atom is approx. equal...
