compute the de broglie wavelength of electron in bohrs first orbit ?
1 Answer
Umakant biswal
from standard info . its clear that the velocity of electron in bohr frst orbit = 2.18 * 10 ^6 m / s
now de broglie wavelength is given by = lambda = h/ mv
h = planks constant = 6.62 * 10 ^ -34
m = mass of an electron = 9.1 * 10 ^ -31
v = velocity of an elecetron
using this lambda = 3.33 * 10 ^ 10 m = 3.33 armstrong
HOPE IT CLEARS
