Which scientist proved the wave nature of light by experiment?
Think it through first, then pick an option.
- a Thales
- b Young
- c Maxwell
- d Becquerel
Answer and explanation
Correct answer: b Young
Thomas Young showed around 1801, with his double-slit experiment, that light behaves as a wave. This is an exam fact beyond the book.
Why the other options are wrong
- a Thales: This is not the answer: Thales was an ancient Greek philosopher; he did not prove the wave nature of light by experiment.
- c Maxwell: This is not the answer: Maxwell showed in theory that light is an electromagnetic wave; the experimental proof of its wave nature is Young's.
- d Becquerel: This is not the answer: Becquerel discovered radioactivity, not the wave nature of light.
