Explain the significance of Heisenberg's uncertainty principle .

Text Solution

Verified by Experts

1) This principle applies for motion of microscopic objects and not so for macroscopic objects .
2) For massive bodies , the uncertainties have no practical importance.
3 ) Microscopic bodies like electrons cannot have fixed paths of motion , according to this principle .
