The kinetic energy of an electron gets tripled, then the de-Broglie wavelength associated with it changes by a factor

A

`1/3`

B

`sqrt3`

C

`1/sqrt3`

D

3

Text Solution

Verified by Experts

The correct Answer is:
C
`lamda = h/(mv) =h/(sqrt(2mk)) implies k. = 3k`
`lamda. = h/(sqrt(2m3k))=h/(sqrt3sqrt(2mk))implies lamda. =lamda/sqrt3`
