If alpha particle, proton and electron move with the same momentum, them their respective de Broglie wavelengths `lamda_(alpha),lamda_(p),lamda_(e)` are related as

A

`lamda_alpha =lamda_p = lamda_e`

B

`lamda_alpha lt lamda_p lt lamda_e`

C

`lamda_alpha gt lamda_p gt lamda_e`

D

`lamda_p gt lamda_e gt lamda_alpha`

Text Solution

Verified by Experts

The correct Answer is:
A
`lamda = h/P , as P_(alpha) = P_(p) = P_(e) implies lamda_(alpha) = lamda_(p) = lamda_(e)`
