An electron, a proton and an alpha particle have K.E. 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) gt lambda_(e) = lambda_(p)`

Text Solution

Verified by Experts

The correct Answer is:
A
`lambda = (h)/(sqrt(2mkE))`
