If an electron and proton are propagating in the form of waves having the same `lambda`, it implies that they have the same

A

energy

B

momentum

C

velocity

D

angular momentum

Text Solution

Verified by Experts

The correct Answer is:
B

Momentum, `p = (h)/(lambda)`
As both electron and proton have same `lambda`, so they have the same momentum
