Uncertainity Principle

Werner Heisenberg, told us that we can never measure simultaneously the position of a moving microscopic particle with perfect accuracy or certainty.
He had said that the more precise we measure the position the less precise the momentum is known and vice versa.
If you are thinking why it is so, then I want to tell you that we can see the object only by illuminating it with light, in the dark we can't see. Do you agree with me.
And light consist of photons (in simple word you know that light is a form of energy). Energy of photon is given by h.v ( h is placks constant and v is frequency).
Okay now you know that frequency is inversely proportional to wavelength.
So according to principle of optics, the accuracy at which particle can be located is inversely proportional to wavelength of light used. The shorter the wavelength used more will be the accuracy in position. But shorter wavelength means higher frequency and higher frequency means higher energy of photon.
Now when this high energy photon strikes the microscopic particle, they transfer energy to microscopic particle and due to which their speed and direction changes ans so we cannot measure accurately its momentum.
So we have seen that how on trying to measure position of the microscopic particle accurately we looses our control over its momentum, and if we try to measure accurately its momentum, we have to illuminate with the light of high wavelength and at that condition we are unable to measure its position accurately.
That's why Heisenberg had said that we can't measure simultaneously the position and momentum of a microscopic particle with absolute accuracy or certainty.
