Question

12 (A): At same velocity, the wavelength of matter wave of proton and electron are different
(R): The mass of electron and proton are different​

Answer 1

Answer:

ANSWER

1) de-Broglie wavelength is given by λ=

p

h

,

Where h is Planck

′

s constant so same for both electron and proton.

p is momentum of the particle, as both have same wavelength so momentum should be same for both of them.

2)Electrons are a type of subatomic particle with a negative charge. ... Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.
