Experiments that revealed light's nature.

Please, I need a list of definitive experiments that revealed light's nature.

Well there's the double slit experiment, light was into places at once so the decided that it was particles that behaved ike waves. Young's fringes showed that light is a wave because superposition takes place (ie. they can cancle out).

1. Double-slit experiment (1801): This experiment, conducted by Thomas Young, showed that light behaves like a wave, exhibiting interference patterns when passed through two slits.

2. Photoelectric effect (1887): This experiment, conducted by Heinrich Hertz and later refined by Albert Einstein, showed that light behaves like a particle, as it can knock electrons off a metal surface.

3. Michelson-Morley experiment (1887): This experiment, conducted by Albert Michelson and Edward Morley, showed that the speed of light is constant, regardless of the observer's motion.

4. Compton scattering (1923): This experiment, conducted by Arthur Compton, demonstrated that light behaves like a particle when interacting with matter, as it can transfer its energy to electrons in a process called scattering.

5. Davisson-Germer experiment (1927): This experiment, conducted by Clinton Davisson and Lester Germer, showed that electrons exhibit wave-like behavior, similar to light, when they are diffracted by a crystal.

6. Laser experiment (1960): This experiment, conducted by Theodore Maiman, showed that light can be amplified and focused into a narrow beam, demonstrating its coherence and monochromaticity.

7. Hanbury Brown and Twiss experiment (1956): This experiment, conducted by Robert Hanbury Brown and Richard Twiss, showed that light behaves like a stream of particles, as they observed photons arriving at a detector in discrete packets.

8. Quantum entanglement experiment (1982): This experiment, conducted by Alain Aspect and colleagues, showed that light can exhibit non-local behavior, where two particles can be connected even when separated by large distances.

9. Bose-Einstein condensate experiment (1995): This experiment, conducted by Eric Cornell and Carl Wieman, showed that light can be manipulated and controlled at the quantum level, leading to the creation of a new state of matter.

10. Gravitational lensing (1919): This experiment, conducted by Arthur Eddington, showed that light is affected by gravity, confirming Einstein's theory of general relativity and providing evidence for the curvature of space-time.
