Question

What is the reason for uncertainty in Heisenberg's uncertainty principle?

Answer 1

Answer:

The uncertainty principle arises from the wave-particle duality. Every particle has a wave associated with it; each particle actually exhibits wavelike behaviour. The particle is most likely to be found in those places where the undulations of the wave are greatest, or most intense.

Answer 2

Answer:

if we went to subatomic level we can't measure both position and velocity of the particlet this is called uncertainty principle
