Explain why the uncertainty principle is significant only for subatomic particles, but not for macroscopic object.

Text Solution

Verified by Experts

The position of subatomic particle can be located accurately by illuminating it with some electromagnetic radiation. The energy of photon associated with such radiation is sufficient to distrub a subatomic particle so that there is uncertainty in the measurement of position and momentum of the subatomic particles. however, this energy is insufficient to distrub a macroscopic object.
