According to wave-particle duality, the De Broglie wavelength is a wavelength manifested in all the objects in quantum mechanics which determines
the probability density of finding the object at a given point
of the configuration space
What is the de Broglie wavelength of the wave associated with an electron that has been accelerated?
1226 nm
.
What is the significance of de Broglie wavelength?
All particles can show wave-like properties. The de Broglie wavelength of a particle
indicates the length scale at which wave-like properties are important for that particle
. De Broglie wavelength is usually represented by the symbol λ or λ
dB
.
What is the de Broglie wavelength associated with Nth Orbital?
[SOLVED] De – Broglie wavelength of electron in nth orbit of H – atom is
(3.18pi)
A .
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.
What has the longest de Broglie wavelength?
Explain. ————–
The electron
has the longer de Broglie wavelength. Since λ = h/p = h/(mvγ) and the proton has a much higher mass, it has larger momentum and hence a shorter wavelength.
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 main point of the de Broglie equation?
λ = h/mv
, where λ is wavelength, h is Planck’s constant, m is the mass of a particle, moving at a velocity v. de Broglie suggested that particles can exhibit properties of waves.
Why de Broglie concept has no significance in our daily life?
The wave nature of matter, however, has no significance for objects of ordinary size
because wavelength of the wave associated with them is too small to be detected
. … This wavelength is too small to be measured, and hence de-Broglie relation has no significance for such a large object.
What has the same de Broglie wavelength?
If a proton and electron have the same de broglie wavelength their momentum will be equal. Hence the correct answer is option (A)
Momentum of electron = momentum of proton
.
What is the de Broglie wavelength of electrons in the beam?
For an electron with KE = 1 eV and rest mass energy 0.511 MeV, the associated DeBroglie wavelength is
1.23 nm
, about a thousand times smaller than a 1 eV photon. (This is why the limiting resolution of an electron microscope is much higher than that of an optical microscope.)
What is the correct relation between de Broglie wavelength of an electron in the nth Bohr orbit?
V – m Which is the correct relation between de-Broglie wavelength of an electron in the nth Bohr orbit and radius of the orbit R? (1)
= n2TR 270R 4TR
(4) A = 276 nh (X-rays and the Atomic Number)
Which of the following is de Broglie equation?
h=p+λ
What is de Broglie’s theory?
De Broglie’s hypothesis of matter waves
postulates that any particle of matter that has linear momentum is also a wave
. The wavelength of a matter wave associated with a particle is inversely proportional to the magnitude of the particle’s linear momentum. The speed of the matter wave is the speed of the particle.
What has the largest de-Broglie wavelength assuming that all have the same velocity?
Electron
has the largest de-broglie wavelength, provided all have equal velocity. Explanation: According to de Broglies wavelength, the wavelength where ‘m’ is the mass and ‘u’ is the velocity.
What has the smallest wavelength at the same velocity?
With equal speeds,
the proton
has the larger momentum and, hence, the shortest wavelength.
