Answer:
True.
Explanation:
To describe the problem of trying to locate a subatomic particle that behaves like a wave, Werner Heisenberg formulated what is now known as the Heisenberg uncertainty principle: it is impossible to know simultaneously both the momentum p (defined as mass times velocity) and the position of a particle with certainty.
Making measurement of the momentum of a particle more precise means that the position must become correspondingly less precise. Similarly, if the position of the particle is known more precisely, its momentum measurement must become less precise.
