Question

*If particles are moving with same velocity, then maximum de Broglie wavelength is for:*

1️⃣ proton
2️⃣ neutron
3️⃣ alpha particle
4️⃣ beta particle​

Answer 1

Answer:

Now, since all the particles are moving with same velocity, the particle with least mass will have maximum de-Broglie wavelength. Out of the given four particles (proton, α− particles, i.e. He nucleus and β− particles, i.e. electrons) β− particles has the lowest mass and therefore it has maximum wavelength.

Answer 2

Answer:

proton!
