Question

An electron, an α- particle and proton have same kinetic energy. Which of these
particles has the shortest by Broglie wavelength?

Answer 1

Answer:

Thus the particle with higher mass has the shortest wavelength. In this case, protons are heavier compared to electrons, and alpha particles are composed of two protons. Hence the alpha particle is the heaviest compared to a proton and an electron. Therefore, the alpha particle has the shortest wavelength.
