State the de Broglie relation and Heisenberg's uncertainty principle.
Original Khojo Papers practice question — not from a past board paper.
Answer
The de Broglie relation is λ = h/mv, so every moving particle has an associated wavelength. Heisenberg's uncertainty principle states that the position and the momentum of a particle cannot both be determined exactly at the same time, the product of the uncertainties being at least h/4π.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Both are why the Bohr picture of fixed orbits had to be replaced by orbitals.
