Which of the following has a longer de Broglie wavelength?
Explanation: Therefore, β-particle has the longest de Broglie wavelength.
Which has longer wavelength electron or proton?
A. The electron. The de Broglie hypothesis says the wavelength of a particle’s matter wave is inversely proportional to its momentum. Therefore the smaller mass and smaller momentum of the electron means that it has a longer wavelength.
When an electron and proton have same de Broglie wavelength they will have equal kinetic energy?
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. The de broglie’s wave equation is only applicable for micro particles.
Which particles has longest wavelength?
electron
The mass of alpha particle = 6.65 × 10-27 kg; Among these four particles, the Lightest particle is an electron; ∴ Hence an electron will have the longest wavelength.
What happens to the de Broglie wavelength of a proton as its velocity increases?
Does the de Broglie wavelength of a proton become longer or shorter as its velocity increases? A. The de Broglie wavelength of a proton becomes longer.
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.
Which of these particles having the same kinetic energy has the largest de Broglie wavelength?
Electron
Electron has the largest de-Broglie wavelength, because de -Broglie wavelength is inversely proportional to the mass of the particle.
Which has the smallest de Broglie wavelength to h2 a proton and electron?
According to the de-Broglie equation λ = h /m×v ; for same value of velocity λ= 1/ m. ∴ O2 Molecule has shortest wavelength.
What is the relationship between momentum and de Broglie wavelength?
Easy one: the electron. The de Broglie wavelength is inversely proportional to momentum. Since the proton has about 2000 times the mass of an electron, it will also have about 2000 times as much momentum when it is traveling at the same velocity as an electron.
Which particle has the largest de-Broglie wavelength?
for the same kinetic energy. (i) Out of given particles, the mass of alpha particle is maximum, so de Broglie wavelength associated with alpha particle is the shortest. (ii) As mass of electron is least, so electron has largest de-Broglie wavelength.
What are the applications of de Broglie waves?
Applications of de Broglie Waves 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.
