A Luz
A Luz é um dos fenômenos mais intrigantes da natureza. Isto decorre do caráter fisiológico de sua percepção e das dificuldades em se lidar com as grandezas envolvidas. Por conta desta complexidade, os aspectos perceptivos e práticos são essenciais na sua compreensão. O conhecimento científico é apresentado segunda a seqüencia histórica. Com noções básicas sobre a formação de imagens, descreve-se a óptica do olho humano e de alguns sistemas ópticos. Das limitações da óptica geométrica surgiu a óptica física. A união com o eletromagnetismo, no final do século XIX, deu origem a Teoria da Relatividade. O século XX ainda nos reservou novas e intrigantes descobertas apresentadas, através das experiências que revelaram a natureza quântica da luz e suas implicações tecnológicas. Este livro faz parte da coleção "Temas atuais em Física" , uma série de livros de divulgação científica realizada em parceria com a Sociedade Brasileira de Física.
