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/(mv)` if v is same, then higher the value of m means lower will be the value of `lamda`.

Thus, `alpha`-particle has the largest mass i.e., shortest wavelength.
