Por esta descoberta, ele recebeu o Pr\u00eamio Nobel de F\u00edsica em 1930, sendo o primeiro asi\u00e1tico e n\u00e3o branco a ter recebido este pr\u00eamio.<\/p>\n<div>O fen\u00f4meno foi o efeito Raman e o homem por tr\u00e1s dele foi C. V. Raman. O efeito Raman demonstra que os f\u00f3tons dispersos n\u00e3o precisam ter a mesma energia (freq\u00fc\u00eancia e comprimento de onda) que os f\u00f3tons incidentes. Perde-se alguma quantidade de energia quando um f\u00f3ton atinge um \u00e1tomo, e cada \u00e1tomo s\u00f3 pode conter uma quantidade espec\u00edfica de energia. O estudo das energias correspondentes \u00e0s mudan\u00e7as de freq\u00fc\u00eancia Raman ajuda a identificar a composi\u00e7\u00e3o e as propriedades dos materiais.<\/div>\n<div>\n<div><img decoding=\"async\" loading=\"lazy\" class=\"alignnone wp-image-1761 size-full\" src=\"https:\/\/www.kolabtree.com\/blog\/wp-content\/uploads\/2017\/02\/raman-krishnan.jpg\" alt=\"raman-krishnan\" width=\"480\" height=\"360\" srcset=\"https:\/\/www.kolabtree.com\/blog\/wp-content\/uploads\/2017\/02\/raman-krishnan.jpg 480w, https:\/\/www.kolabtree.com\/blog\/wp-content\/uploads\/2017\/02\/raman-krishnan-300x225.jpg 300w\" sizes=\"(max-width: 480px) 100vw, 480px\" \/><\/div>\n<div>C.V.

S. Krishnan, who contributed enormously to Raman&#8217;s studies and experiments. Krishnan, who was working in Madras Christian College, moved to Calcutta in 1920 to work with Raman. During the years 1925 to 1928, Krishnan authored singly or jointly 16 papers, under Raman&#8217;s tutelage. He was the one who first gave Raman a demonstration of the scattering. Between Feb 19th and 26th, 1928, Krishnan performed many experiments that proved the inelastic scattering of light. The discovery of the Raman effect was made jointly by Raman and Krishnan on February 28th, which is now celebrated as National Science Day.<\/div>\n<div><\/div>\n<div>Depois que Raman ganhou o Pr\u00eamio Nobel em 1930, houve muita controv\u00e9rsia que sugeriu que Krishnan n\u00e3o recebia cr\u00e9dito suficiente por sua contribui\u00e7\u00e3o. No entanto, a contribui\u00e7\u00e3o de Krishnan n\u00e3o foi suficiente, <a href=\"http:\/\/madrasmusings.com\/Vol%2022%20No%2022\/the-illustrious-scientist-who-teamed-with-cv-raman.html\">Krishnan tinha isto a dizer<\/a>:<\/div>\n<div><\/div>\n<div>\"Se voc\u00ea ler a palestra Nobel, que \u00e9 um relato verdadeiro e honesto sobre o progresso e a hist\u00f3ria do assunto, o Professor nomeia todos os seus colaboradores para come\u00e7ar com K. R. Ramanathan dando a todos (e inclusive a mim) o devido cr\u00e9dito. Sempre em palestras p\u00fablicas, ele sempre mencionou que eu colaborei com ele na descoberta do efeito e que nossa colabora\u00e7\u00e3o foi semelhante \u00e0 de Bowen e Millikan que foi realmente um elogio\".<\/div>\n<\/div>\n<div>Embora C.
