Is proton electron and alpha-particle have equal kinetic energy their de-Broglie wavelength would be in the order?

An electron, an alpha-particle and a proton have the same kinetic energy. It means smallest is the particle mass, largest is the de-Broglie wavelength associated with it. Since the mass of electron is least out of the given particles, hence d-Broglie wavelength is largest for electron and least for α-particle.

Which particles in motion having the same kinetic energy has the shortest wavelength?

Detailed Solution. Concept: The wavelength of any charged particle due to its motion is called the de-Broglie wavelength. Hence, the shortest wavelength from all the above-given particles is the alpha-particle.

Would an electron or proton have a larger wavelength if they had the same kinetic energy?

An electron has the larger wavelength. Reason : de-Broglie wavelength in terms of kinetic energy is λ=h√2mEkα=1√m for the same kinetic energy. As an electron has a smaller mass than a proton, an electron an electron has larger de-Broglie wavelength than a proton for the same kinetic energy.

When moving with the same velocity which out of electron proton and alpha-particle has the largest de-Broglie wavelength give reason?

An electron, an alpha-particle and a proton have the same kinetic energy. Which one of these particles has the largest de-Broglie wavelength? Wavelength and mass has inverse dependence. Since, mass of electron is the least out of all the three particles therefore, electron has the largest de-Broglie wavelength.

What is the ratio of de-Broglie wavelength of proton and alpha particle of same energy?

λ=h√2mEkλαλp=√mpmα=√14=12.

Which has more velocity alpha particle or proton?

Close to the Sun, α particles have a higher bulk speed and temperature than protons due to the preferential acceleration and heating of minor ions caused by wave–particle interactions (e.g., Marsch et al.

What has shortest de-Broglie wavelength?

neutron
e) The neutron has the shortest de Broglie wavelength.

Which particle has the shortest wavelength?

alpha particle
The mass of alpha particle = 6.65 × 10-27 kg; Among these four particles, the heaviest particle is alpha particle; ∴ Hence the alpha particle will have the shortest wavelength.

Does a proton or electron have a longer wavelength?

Therefore the smaller mass and smaller momentum of the electron means that it has a longer wavelength. The longer de Broglie wavelength of particle 1 means that it has less momentum than particle 2 because de Broglie wavlength is inversely proportional to momentum.

Which has more wavelength electron or a proton?

Answer: The de Broglie wavelength of a particle is inversely proportional to its momentum p = m v; since a proton is about 1800 times more massive than an electron, its momentum at the same speed is 1800 times that of an electron, and therefore its wavelength 1800 times smaller. The electron has the longer wavelength.

What is the ratio of de Broglie wavelength of proton and alpha particle of same energy?

Which of the following particles moving with the same speed has the longest de Broglie wavelength?

Explanation: Therefore, β-particle has the longest de Broglie wavelength.
