If the kinetic energy of a electron , it's debroglie wavelength changes by the factor

A

`2`

B

`(1)/(2)`

C

`sqrt(2)`

D

`(1)/(sqrt(2))`

Text Solution

Verified by Experts

The correct Answer is:
D
de- Broglle wavelenght ,
` lambda= (h)/(p) (h)/(sqrt(2 m (K.E)) :. Lambda prop (1)/(sqrt(K.E))`
if K.E is doubled, wavelength became ` (1)/(sqrt(2))`
