It travelling at same speeds, whichof the following mater waves have the shortest wavelength?

A

Electron

B

Alpha particle `(He^(2+))`

C

Neutron

D

Proton

Text Solution

Verified by Experts

The correct Answer is:
B
`lambda=(h)/(m v)`
h and `v` are both constants. Therefore , `alpha`-particle `(He^(2+))` with maximum mass has the shortest wavelength.
