An electron, a proton and an alpha particle have KE of 16E, 4E and E respectively. What is the qualitative order of their de-Broglie wavelengths?

A

`lambda_(e) gt lambda_(p) gt lambda_(alpha)`

B

`lambda_(p) = lambda_(alpha) gt lambda_(e)`

C

`lambda_(p) lt lambda_(c) lt lambda_(alpha)`

D

`lambda_(alpha) lt lambda_(e) = lambda_(p)`

Text Solution
