DE BROGLIE’S EQUATION
In 1924 de Broglie suggested that matter and hence electron(electron is treated like a particle in Bohr’s theory) ,like radiations has a dual character i.e. wave and particle. This concept gave rise to the wave mechanical theory of matter according to which the […]
RADIATION
Radiation is the fastest mode of heat transmission in which the energy transfer from one point to another takes place in the form of electromagnetic waves. According to quantum theory, radiation travels in space in the form of energy packets called photons. The energy of photon is […]
NEWTON’S LAWS OF MOTION
FIRST LAW OF MOTION
Newton’s first law states that
A body at rest will remain at rest and a body in motion will remain in motion in a straight line with a constant velocity unless an external force acts on the body.
Thus we see that if […]
