Find the ratio of de Broglie wavelengths...

Find the ratio of de Broglie wavelengths of an `alpha` -perticle and a deutron it they are accelearating through the sam potenital difference .

A

`1`

B

`sqrt(2)`

C

`1// sqrt(2)`

D

none of the above

Text Solution

Verified by Experts

The correct Answer is:
A
`(lamda_(P))/(lamda_(N))=(((h)/(m_(P)V_(P))))/(((h)/(m_(N)V_(N))))=(m_(N))/(m_(P))`
`(because V_(P)=V_(N))=1`
