In Quantum Mechanics, nothing is certain, but probabilistic. This means that you can just say that the chance of finding a particle in a particular region of space is p% (p<100). p =" 100" p =" 0," style="color: rgb(0, 153, 0);"> Heisenberg Uncertainty Principle. According to this principle, the uncertainties of the conjugate quantities are related by the formula - delta(P)*delta(Q) greater than or equal to h divided by 4*pi, where h = 6.63*10^-34 Js is called the Planck's constant and pi = 3.1416. In this formula, delta(P) is the uncertainty of measurement in the quantity P and delta(Q) is the uncertainty of measurement in the quantity Q. This means if you measure the quantity P more accurately, the measurement of the quantity Q will be less accurate. For example, if we are making the measurements of the position and the momentum of a particle, the more accurately we measure the position, the more inaccurate or uncertain will be the momentum, always giving the product of the two uncertainties greater than or equal to h divided by 4*pi.

WOW !!

The video is great!!

But I could not understand why the circle becomes wider and wider when the slit becomes narrower and narrower below certain size.May be it is not understandable by common brain.
