THOMSON'S ATOMIC MODEL:-
According to Thomson's atomic model positive charge is distributed uniformly over the entire body of the atom while the electrons are embedded in it. Similar to the seeds in a water melon.
Thomson's model failed to explain observed spectra emitted by an atom .
Q Define: Drift velocity. Drift velocity is described as the velocity with which free electrons get drifted towards the positive terminal, when an electric field is applied.
Two waves of equal frequency have amplitudes 2 units and 3 units respectively. When they superpose coherently the intensity of the resultant wave is I 1 . The intens

KINEMATICS II 1. The concept of the derivative of the function is exceptionally important. The derivative shows that how fast the function changes when its argument is changed.
Hall effect: While charged particles pass through a tube that has both an electric field & a magnetic field (perpendicular to the electric field) exist in it, only certain vel
