Davisson and Germer Experiment, for the first time, proved the wave nature of electrons and verified the de Broglie equation. de Broglie argued the dual nature of matter back in 1924, but it was only later that Davisson and Germer experiment verified the results. The results established the first experimental proof of quantum mechanics. In this experiment, we will study the scattering of electrons by a Ni crystal. Let’s find out more.

Aditya Chauhan 5 years, 9 months ago

The experimental setup for the Davisson and Germer experiment is enclosed within a vacuum chamber. Thus the deflection and scattering of electrons by the medium are prevented. The main parts of the experimental setup are as follows: Electron gun: An electron gun is a Tungsten filament that emits electrons via thermionic emission i.e. it emits electrons when heated to a particular temperature. Electrostatic particle accelerator: Two opposite charged plates (positive and negative plate) are used to accelerate the electrons at a known potential. Collimator: The accelerator is enclosed within a cylinder that has a narrow passage for the electrons along its axis. Its function is to render a narrow and straight (collimated) beam of electrons ready for acceleration. Target: The target is a Nickel crystal. The electron beam is fired normally on the Nickel crystal. The crystal is placed such that it can be rotated about a fixed axis. Detector: A detector is used to capture the scattered electrons from the Ni crystal. The detector can be moved in a semicircular arc as shown in the diagram above.

Hey dont get stressed it will decrease yoir performence Einstein's Photoelectric Equation: The minimum energy required by an electron to come out of the surface of the metal is called the photoelectric work function (∅o) of the metal. The remaining energy (hν – ∅o) is the maximum kinetic energy of the electron with which a photoelectron will be ejected.

Laws of Photoelectric Emission The number of electrons emitted per second is directly proportional to the amount of light incident on the surface. The energy of the emitted electrons is free from the amount of the photons incident on the surface, and it depends on the frequency of the light flux.

Indica of megasthenese,arthshastra of kautilya,mudra rakshash of vishakha dutta,ashokan inscriptions. (Explanation required)

Yogita Ingle 5 years, 9 months ago

Sources to reconstruct the history of the Mauryas
(i) Archaeological finds, especially sculpture.
(ii) Contemporary works, such as the account of Megasthenes.
(iii) Arthashastra, probably composed by Kautilya or Chanakya.
(iv) The Mauryas are mentioned in later Buddhist and Jaina.
(v) Puranic literature, as well as in Sanskrit literary works.
(vi) The inscriptions of Asoka on rocks and pillars.
(vii) Stupas

Because electric field lines emerges from negative charge and goes into positive charge.... they never return back to negative charge .....due to which they do not form closed loops...

Prabhat Emmanuel 5 years, 9 months ago

Because No electric field lines exist inside close loop .

Lucky R J 5 years, 9 months ago

Because there is no electric field inside the loop

Yogita Ingle 5 years, 9 months ago

The electric line of force is the path occupied by a unit positive test charge when placed along the line. If electric field line is a closed loop it means that positive test charge would come back to the positive source charge i.e initially there was repulsion and now it has turned into the attraction, which is impossible .
