MCQ
According to the Heisenberg uncertainty principle:
  • A
    Momentum of an electron can be found exactly if its position is known.
  • B
    The lowest energy of an atom can hold only one electron.
  • C
    Light has a dual nature- wave and photon.
  • D
    There is a limit to the accuracy of the measurement of subatomic particles.

Answer

  1. There is a limit to the accuracy of the measurement of subatomic particles.

Explanation:

According to the Heisenberg uncertainty principle, the position and the momentum of the particle cannot be measured accurately simultaneously. Thus there is a limitation to the accuracy of the measurement of subatomic particles.
