Quantum Physics Quiz

The Heisenberg Uncertainty Principle states that it's impossible to measure two quantum variables concurrently with accuracy. It challenges the Newtonian physics belief and provides insights into the behavior of sub-atomic particles.

Werner Heisenberg formulated the Heisenberg Uncertainty Principle in 1927.

The principle applies to pairs of variables like position and momentum, and energy and time, termed 'conjugate pairs'.

<p>The wave-particle duality refers to the idea that particles can exhibit both wave-like and particle-like behavior, depending on the experimental setup. This duality exists in reference to matter's basic properties, where it can exist in particle form at one time and in wave form at another time.</p> Signup and view all the answers

<p>The way energy is transmitted varies between particles and waves. For example, when a particle moves, it transfers kinetic energy, while when a wave moves, it causes potential energy to be converted to kinetic energy.</p> Signup and view all the answers

<p>For instance, when a pebble is thrown from one point to another, kinetic energy is transferred from the pebble's starting point to the point of landing, representing particle behavior. In contrast, when a wave moves in the ocean, potential energy is converted to kinetic energy, showcasing wave behavior.</p> Signup and view all the answers
