Rutherford and Light Experiments

The video explores the fundamental concepts of physics, focusing on three groundbreaking experiments. It begins with an introduction to physics and its unanswered questions. The first experiment by Henry Cavendish measures gravity and establishes the gravitational constant. The second experiment by Thomas Young demonstrates light's wave-particle duality, challenging Newton's particle theory. The third experiment by Ernest Rutherford reveals the atomic nucleus, leading to the modern atomic model. The video concludes with an invitation to discuss other important experiments and subscribe for more content.
