Young's experiment, performed in the early 1800s, played a vital part in the acceptance of the wave theory of light, vanquishing the corpuscular theory of light proposed by Isaac Newton, which had been the accepted model of light propagation in the 17th and 18th centuries.
O experimento de Young, realizado a principios de 1800, xogou un papel vital na aceptación da teoría da onda de luz, vencendo a teoría corpuscular da luz proposta por Isaac Newton, que fora o modelo aceptado de propagación da luz nos séculos XVII e XVIII.
