The uncertainty in the position of a particle equal to the de-Broglie wavelength uncertainty in its momentum will be…….

A

`(h)/(lambda)`

B

`(2h)/(3lambda)`

C

`(lambda)/(h)`

D

`(3lambda)/(2h)`

Text Solution

Verified by Experts

The correct Answer is:
A
`Deltax.Deltap=h therefore Deltap=(h)/(Deltax)` but `Deltax=lambda therefore Deltap=(h)/(lambda)`
