Description

Heisenberg uncertainty principle @candle academy Pakistan.
in lecture 14 of chapter 18 dawn of modern physics we have explained the Heisenberg uncertainty principle.

following are subtopics of this lecture.

what is uncertainty in measurements?

uncertainty in the measurement is the error induced in the measurement due to instruments. the object having dimensions less than the least count of measuring instruments cannot be measured accurately.

uncertainty and quantum particles.

uncertainty in the quantum particles is not due to the measuring instruments , it is due to the dual nature of light.

what is Heisenberg uncertainty principle?

Heisenberg uncertainty principle states that no two aspects of quantum particle can be measured simultaneously with 100% accuracy.if one quantity is measured with accuracy The other becomes uncertain.

explanation of Heisenberg uncertainty principle.

Heisenberg uncertainty principle can also be stated as the product of uncertainty in any two aspects of quantum particle is equal to Planck's constant.
for example the product of uncertainty of momentum and uncertainty in position is almost equal to Planck's constant.

uncertainty in macro particles.

the uncertainty in the macro objects cannot be observed because the macro objects have associated wavelength very much shorter and cannot be observed.
