What will be the ratio of de - Broglie wavelengths of proton and `alpha` - particle of same energy ?

A

1

B

2

C

4

D

`0.25`

Text Solution

Verified by Experts

The correct Answer is:
B
de-Broglie wave length
`lamda = (lamda)/(P)=(lamda)/(sqrt(2km)) rArr (lamda_(P))/(lamda_(alpha)) = sqrt((m_(alpha))/(m_(rho)))=2`
