Question

is there is no techniques to find the exact location and momentum of microscopic particle like electron simultaneously? elaborate ​

Answer 1

Hey mate!!!!

Well if you are trying to find a way to do that just remember heisenberg's equation has a more than sign along with equal to and that deals with the accuracy in error also.

As you might have known electron is a wave as well as particle. And being informative, anybody can tell you that localisation of wave makes it lose its direction and once a wave loses direction . Its momentum , no matter how accurate your tools are, can not be measured precisely.

Actually err.....just do not get confused but if you look at formulas of wave function, you will get an idea that for accurate position wave function must be 0 all over except actual position but for momentum non zero value of wave function is required except for original position also. Hence you can say such wave function is not possible . So , we can not measure a moving electron's actual position and momentum at same time with full accuracy

Answer 2

There may be a flaw in the explanation that I am going to make because uncertainty principle is the heart of quantum mechanics and cannot be violated.

Suppose we take particles that are entangled due to their interactions and are separated at a distance.Now you measure the position x1 of the particles to huge certainty hence making momentum p1 of the particle highly uncertain.On the entangled particle make the momentum measurement p2 to huge certainty thus making the position x2 highly uncertain.Since the particles pairs are entangled using p2 we can deduce p1 and using x1 we can deduce x2. Thus determining the position and momentum at the same time.

Due to a classical explanation of uncertainty principle given in our text tells that to measure the position of a particle we bombarded it with a photon which result in momentum transfer hence changing its momentum.Looking and reading along this lines tells how determination of momentum and position of entangled particles is possible

But as luckyjoshi615 explained uncertainty principle is much above that.Before observation particles are in a superposition of quantum states and measurement result in collapse of quantum state. Measurement of position requires wavefuction collapse to a single point which result in the loss of momentum information and vice versa.This is basically a mathematical framework developed based on uncertainty principle.

But as the Copenhagen interpretation ,that the observation changes reality ,I truly disagrees with it as Einstein told God doesn't play dice.Or as the famous question "if tree falls and no one is around it to hear does it makes sound".I truly believes present day quantum mechanics is INCOMPLETE lacking some major aspects.
