Quantum Tunneling Explained in Simple Words for Beginners

What is quantum tunneling? In this video, we explain quantum tunneling in simple words — from wave-particle duality and probability waves to how particles pass through barriers they shouldn't be able to cross. Learn why quantum tunneling powers the Sun's nuclear fusion and how it enables atomic-level microscopy. Whether you're a physics student, preparing for an exam, or just fascinated by the quantum world, this beginner-friendly animated explainer makes one of quantum mechanics' strangest phenomena easy to understand.
