Answer:
1.Mathematically, the Heisenberg uncertainty principle is a lower bound on the product of uncertainties of a pair of conjugate variables. The most well-known expression takes the position and momentum to be the conjugate variables: σ x σ p ≥ ℏ 2 . ... σxσp≥2ℏ.
2.The Heisenberg uncertainty principle is a law in quantum mechanics that limits how accurately you can measure two related variables. Specifically, it says that the more accurately you measure the momentum (or velocity) of a particle, the less accurately you can know its position, and vice versa.
3.It was observed that : (i) most of the α– particles passed through the gold foil undeflected. (ii) a small fraction of the α–particles was deflected by small angles. (iii) a very few α– particles (∼1 in 20,000) bounced back, that is, were deflected by nearly 180°.
