Question

Why Heisenberg principle is applied for microscopic particles​

Answer 1

Answer:

Heisenberg's Uncertainty Principle states that there is inherent uncertainty in the act of measuring a variable of a particle. Commonly applied to the position and momentum of a particle, the principle states that the more precisely the position is known the more uncertain the momentum is and vice versa.

Answer 2

Answer:

Therefore, macroscopic objects does not obeys the uncertainty principle. The same cannot be said of microscopic objects because their wave-like properties become dominant. It's not possible to get a clear value of position and momentum at the same time for a wave, hence the uncertainty principle comes into play ...

Explanation:

Heisenberg's uncertainty principle is not valid for macroscopic objects and objects at rest. It is applicable for moving microscopic particles.
