Wave-Particle Duality and the Frightening Consequences
Professor Roy Sambles, FRS. Past President of IOP
Three of the greatest Western scientists were distracted by the question ‘What exactly is light?’ Newton rhetorically suggested that rays of light were ‘very small bodies emitted from shining substances’. Young, with his double slit experiment, provided convincing proof of the wave characteristic of light. Then Einstein, by explaining the photoelectric effect, developed a quantum theory of light. But who is actually correct? All are! This demonstration lecture will explore some of the disturbing aspects of wave-particle duality.
