de-Broglie proposed dual nature for electron moving. The wavelength is given by the equations lambda = (h)/(m u) . Later on Heisenburg proposed. The total incertainly uncertainity principle as. If uncertainity in position an momentum of an electron are same, then uncertainty in its velocity can be given by

In the light of Heisenburg uncertainty principle, which radiation photon can locate the position of electron in an atom most precisely?

(A) Schrodinger wave equation (B) Heisenberg uncertainty principle (C) Millikan oil drop experiment (D) Chadwick.s discovery of neutron Of the scientific milestones listed above, which is the most ancient and most modern respectively ?
