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)lt lamda_(e)lt lamda_alpha`

Text Solution

Verified by Experts

The correct Answer is:
A
de Broglie wavelength `lamda =(h)/(p)`
where symbols have their usual meaning.
`:. p_(alpha) = p_(p) = p_(e)`
`:. Lamda_(alpha) = lamda_(p) = lamda_(e)`
