What is wave-particle duality?

• Wave-particle duality is the idea that waves can be converted into solid objects.
• Wave-particle duality states that particles can only behave as waves.
• Wave-particle duality refers to the phenomenon where light can only behave as a particle.
• Wave-particle duality is the concept that particles, like electrons and photons, exhibit both wave and particle characteristics.

What is Heisenberg's uncertainty principle?

• It states that particles can be in two places at once.
• It describes the behavior of classical mechanics in large systems.
• Heisenberg's uncertainty principle is a fundamental concept in quantum mechanics that limits the precision of measurements of certain pairs of complementary variables.
• It asserts that energy can be created from nothing.

What is an atomic orbital?

• An atomic orbital is a region in an atom where there is a high probability of finding an electron.
