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

Options

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

Answer

D

Explanation

(d) `lamda = v`
then `lamda = (h)/(mV)`
or `lamda^2 = (h)/(m)`
So, `lamda = sqrt((h)/(m))`.
