Question

According to the Heisenberg uncertainty principle:

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

Answer 1

The correct option is E There is a limit to the accuracy of the measurement of subatomic particles.

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.
