Which of the following scientists formulated the 'Uncertainty Principle', stating that exact position and momentum of an electron cannot be simultaneously known?
Correct Answer: Option C
Explanation:
Werner Heisenberg, a German theoretical physicist, published his famous Uncertainty Principle in 1927. The principle dictates a fundamental limit to precision at the quantum level: the more precisely the position of a particle (like an electron) is determined, the less precisely its momentum can be known, and vice versa. Mathematically, delta_x * delta_p >= h/(4pi).
