Nascido na cidade de Moga, no estado do Punjab, Kapany graduou-se na Agra University em Dehradun, completou seus estudos avan\u00E7ados em \u00F3ptica no Imperial College of Science and Technology de Londres, recebeu seu Ph.D. na University of London em 1955 e vive nos Estados Unidos desde a metade dos anos 1960. Em 1952, com base nos estudos efetuados pelo f\u00EDsico ingl\u00EAs John Tyndall de que a luz poderia descrever um trajet\u00F3ria curva dentro de um material (no experimento de Tyndall esse material era a \u00E1gua), Kapany p\u00F4de concluir suas experi\u00EAncias que o levaram \u00E0 inven\u00E7\u00E3o da fibra \u00F3ptica. A fibra \u00F3ptica \u00E9 um excelente meio de transmiss\u00E3o utilizado em sistemas que exigem alta largura de banda, tais como: o sistema telef\u00F4nico, videoconfer\u00EAncia, redes locais, etc. H\u00E1 basicamente duas vantagens das fibras \u00F3pticas em rela\u00E7\u00E3o aos cabos met\u00E1licos: A fibra \u00F3ptica \u00E9 totalmente imune a interfer\u00EAncias eletromagn\u00E9ticas, o que significa que os dados n\u00E3o ser\u00E3o corrompidos durante a transmiss\u00E3o. Outra vantagem \u00E9 que a fibra \u00F3ptica n\u00E3o conduz corrente el\u00E9trica, logo n\u00E3o haver\u00E1 problemas com eletricidade, como problemas de diferen\u00E7a de potencial el\u00E9trico ou problemas com raios. O princ\u00EDpio fundamental que rege o funcionamento das fibras \u00F3pticas \u00E9 o fen\u00F4meno f\u00EDsico denominado reflex\u00E3o total da luz. Para que haja a reflex\u00E3o total, a luz deve sair de um meio mais refringente para um meio menos refringente, e o \u00E2ngulo de incid\u00EAncia deve ser igual ou maior do que o \u00E2ngulo limite."@pt , "English: Narinder Singh Kapany, Punjabi: \u0A28\u0A30\u0A3F\u0A70\u0A26\u0A30 \u0A38\u0A3F\u0A70\u0A18 is widely acknowledged as the father of optical fiber.
