3 Physics Experiments that Changed the World

The video explores three groundbreaking physics experiments. Henry Cavendish's 1797 experiment measured gravitational force, leading to the gravitational constant. Thomas Young's early 19th-century experiment demonstrated light's wave properties, challenging Newton's particle theory and contributing to wave-particle duality. Ernest Rutherford's 1909 experiment refuted the plum pudding model, revealing the atomic nucleus and shaping modern nuclear physics.

What implications did Cavendish's findings have on the understanding of gravitational force?

What was the plum pudding model, and why was it deemed insufficient by Rutherford?

Describe the experimental setup used by Rutherford and his colleagues in 1909.
