1227A˚

What is the value of de-Broglie wavelength of an electron when it is accelerated from rest through a potential difference of 150 V?


The de-Broglie wavelength associated with a material particle when it is accelerated through a potential difference of 150V is 1Å.

What is the de-Broglie wavelength of an electron whose kinetic energy is 1.0 eV?

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.

What is the value of de-Broglie wavelength of an electron when it is accelerated?

1.58 Angstrom
So, the de-Broglie wavelength of an electron beam when accelerated through a potential difference of 60 V will be 1.58 Angstrom.

What is the value of de Broglie wavelength?

1. The wave properties of matter are only observable for very small objects, de Broglie wavelength of a double-slit interference pattern is produced by using electrons as the source. 10 eV electrons (which is the typical energy of an electron in an electron microscope): de Broglie wavelength = 3.9 x 10-10 m.

What is the de Broglie wavelength of electron accelerated by 100v?

1.227√Vnm
Here, V=100 Volts. The de- Broglie wavelength λ is λ=1.227√Vnm.

What is the de Broglie wavelength of an 800 eV electron?

λ=0.388 nm .

How do you find de Broglie wavelength with kinetic energy?

The kinetic energy of the electrons accelerated through a potential difference (voltage) V was E = ½mv2 = p2/(2m) = eV and the de Broglie formula then yields λ = h/(2meV)1/2, where e and m are the charge and the mass of the electron respectively.

What is Toppr de Broglie wavelength?

The de Broglie wavelength is the wavelength, associated with a massive particle and is related to its momentum, p, through the Planck constant, h. In other words, you can say that matter also behaves like waves.
