Heisenberg's uncertainty principle rules out the exact simultaneous measurement of (1) probability and intensity (2) energy and velocity (3) charge density and radius (4) Position and momentum

We can pin point an aeroplane moving in the sky, whatever may be its speed i.e., we can locate both its exact position as wellas direction . However, it is not possible to doso in case of a moving microscopic particle such as electron. In fact, we cannot see any such particle without disturbing it. This has been stated by Heisenberg in the form of uncertainty principle. The mathematical form of this principle is : Deltax.DeltaP ge (h)/(4pi) (constant). Since the product of Deltax and Deltap(m Delta upsilon) is constant , if one is very small, the other is bound to be large. The principle as such has no significance in daily life since it applies to those particles which we can not see. Heisenberg's uncertainty principle rules out the exact simultaneous measurement of

What is Heisenberg's uncertainty principal

Heisenberg uncertainty principal is not valid for

It is not possible to determine preciselt both the position and momentum (or velocity) of a small moving particle such as electron, proton etc. This is known as Heisenber uncertainty principle. The mathemactical form of this principle is : Delta x.Delta p ge (h)/(4pi) (constant) However this principle is irrevalent in case of bigger particles such as a cup, ball, car etc., that we come across in our daily life. In case of small microscopic particles, Heisenberg's uncertainty principle rules out simultaneous exact determination of their

It is impossible to determine simaltancously the position of velocity of small mictroscopic particle such as electron , proton or neutron with accoracy .This is called Heisenberg's uncertainty principal, Malthematically, it is represenites as Delta x. Delta p ge (h)/(4pi) Delta x is uncertainty in position Delta p is uncertainty in momentum

A german physicist gae a principle about the uncertainties in simultaneous measurement of position and momentum of small particles. According to that physicist. It is impossible to measure simultaneously the position and momentum of small particle with absolute accuracy or certainty. if an attempt is made to measure any one of these two quantities with higher accuracy, the other becomes less accurate. The produce of the uncertainty in position (Deltax) and uncertainty momentum (Delta p) is always constant and is equal to or greater than h//4pi , where h is Planck's constant i.e. (Deltax ) (Deltap) ge (h)/(4pi) If uncertainty in momentum is twice the uncertainty in position of an electron then uncertainty in velocity is: [bar(h)=(h)/(2pi)]
