Is electron really a particle or wave?
Upto the year 1924, electron was exclusively regarded as a particle. However, in 1924, de-Broglie suggested that an electron behaves both as a material particle and as a wave. Just like light, some experimental facts can be explained by assuming electrons as..
Probability Picture of Electrons and Concept of Atomic Orbital (Wave Mechanical Treatment)
The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolve around the nucleus in certain well-defined circular orbits. But the idea of uncertainty in posi..
Matter Waves
>This is called as dual nature of mater. The radiation has a dual aspect behaving either as waves or as particles (waves when it interferes, diffracts and particles in a photocell). Einstein showed that a particle having a finite mass has been supposed to be associated with a de..
Discovery of Electrons
Production of cathode rays - In 1885, Sir William Crookes carried out a series of investigations into the behaviour of metals heated in a vacuum. The experiment of Crookes and others showed that a heated cathode produced a stream of radiation, which could cause gases at low pressure to glow and whi..

In the physical sense, y gives the amplitude of the wave associated with the electron. It is known that in case of light waves, the square of the amplitude of the wave at a point is proportional to the intensity of light. Extending the same concept to..

Sky Wave Propagation
Sky waves are the AM radio waves, which are received after being reflected from the ionosphere. The propagation of radio wave signals from one point to another via reflection from ionosphere is known as sky wave propagation. The sky wave propagatio..
Probability picture of an electron
According to Heisenberg's uncertainty principle, it is impossible to describe the exact position of an electron at a given moment in terms of position, we can speak of most probable regions where the probability of finding an electron in the space around the nucleus of an atom ..
Why electron cannot exist in the nucleus?
The value of uncertainty in velocity, D v is much higher than the velocity of light (3.0 x 10 8 ms - 1 ) and therefore, it is not possible. Hence an electron cannot be found within the atomic nucleus. In 1927, Erwin Schrodinger described the behavior of electrons around the nucl..
Elementary Idea of Electron Microscope
In optical microscope, the ray of light can be bent by a lens system. By placing the object and the lens system in such a way, we control the direction of the ray to get a magnified image of the object. Since as 'electron' carriers charge it is possible to change the direction of a e..
