What is the de Broglie wavelength of an electron after being accelerated through a potential difference of 25 kV in a television set?
What is the deBroglie wavelength of an electron after being accelerated through a potential difference of 25 kV in a television set? Solution: λ = h/p, E = p 2 /(2m), p = √(2mE), λ = h/√(2mE) . The energy of the electron is 25000 eV * 1.6*10 – 19 J/eV = 4*10 – 15 J.
Why de Broglie wavelength is not observed in our daily life?
De-Broglie wavelength associated with a body of mass m, moving with velocity v is given by λ=hmv Since, the mass of of the object hence the de-Broglie wavelength associated with it is quite small hence it is not visible. Hence the wave nature of matter is not more apparent to our daily observations.
What is the de Broglie wavelength of an electron associated with?
The de Broglie wavelength is the wavelength, λ, associated with a object and is related to its momentum and mass .
What is the de Broglie wavelength of an electron subjected to a potential V?
The de Broglie wavelength λ=1.23 x 10−9m . If a charge of 1 Coulomb is moved through a potential difference of 1 Volt then 1 Joule of work is done. This is how the Volt is defined. So if a charge of e coulombs is moved through a potential difference of V volts then the work done is eV Joules.
What is the formula of de Broglie wavelength?
Apply the de Broglie wave equation λ=hmv λ = h m v to solve for the wavelength of the moving electron.
Which of the following has the largest de Broglie wavelength?
Electron has the largest de-broglie wavelength, provided all have equal velocity.
What happens when an electron is accelerated through a potential difference?
An electron accelerated through a potential difference of 1 V is given an energy of 1 eV . ... A potential difference of 100,000 V (100 kV) will give an electron an energy of 100,000 eV (100 keV), and so on. Similarly, an ion with a double positive charge accelerated through 100 V will be given 200 eV of energy.
What is the most important application of De Broglie concept?
Structure of Atom
What is the most important application of de-Broglie concept? Its most important use is in the construction of electron microscope which is used in the measurement of objects of very small size.
What is the wavelength associated with an electron when it is accelerated with a potential of 100v?
Here, V=100 Volts. The de- Broglie wavelength λ is λ=1.227√Vnm . =1.227√100=1.22710=0.1227=0.123nm.
What is the difference between wavelength and De Broglie wavelength?
The key difference between De Broglie wavelength and wavelength is that De Broglie wavelength describes the wave properties of a large particle , whereas wavelength describes the wave properties of waves. ... Therefore, we can measure it as the distance between consecutive corresponding points of the same phase on the wave.
Which experiment proves the validity of de Broglie’s hypothesis?
The Davisson and Germer experiment demonstrated the wave nature of the electrons, confirming the earlier hypothesis of de Broglie. Electrons exhibit diffraction when they are scattered from crystals whose atoms are spaced appropriately.
Why wave nature is not observed in our daily experience?
As the value of Plank’s constant is very small,so the wavelength associated with ordinary object is so small and is difficult to observe. In our daily observations we deal with the objects having larger mass and smaller velocity , that is why the wave nature of such objects is not more apparent in our daily life.
