If wavelength is equal to the distance travelled by the electron in one second then

Options

A. `lambda = h//p`
B. `lambda = h//m`
C. `lambda = sqrt(h//p)`
D. `lambda = sqrt(h//m)`

Answer

D

Explanation

`lambda = (h)/(mv)` distance travelled in one second by velocity `bar V = vcm = olambda`
`lambda = (h)/(m lambda) rArr lambda^(2) = (h)/(m) rArr lambda = sqrt((h)/(m))`
