Per questa scoperta, ricevette il premio Nobel per la fisica nel 1930, essendo il primo asiatico e non bianco ad aver ricevuto questo alloro.<\/p>\n<div>Il fenomeno era l'effetto Raman e l'uomo dietro di esso era C. V. Raman. L'effetto Raman dimostra che i fotoni dispersi non devono necessariamente avere la stessa energia (frequenza e lunghezza d'onda) dei fotoni incidenti. Una certa quantit\u00e0 di energia viene persa quando un fotone colpisce un atomo, e ogni atomo pu\u00f2 contenere solo una specifica quantit\u00e0 di energia. Lo studio delle energie corrispondenti agli spostamenti di frequenza Raman aiuta a identificare la composizione e le propriet\u00e0 dei materiali.<\/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>Dopo che Raman vinse il premio Nobel nel 1930, ci furono molte polemiche che suggerivano che Krishnan non avesse ricevuto abbastanza credito per il suo contributo. Tuttavia, <a href=\"http:\/\/madrasmusings.com\/Vol%2022%20No%2022\/the-illustrious-scientist-who-teamed-with-cv-raman.html\">Krishnan ha detto questo<\/a>:<\/div>\n<div><\/div>\n<div>\"Se leggete la conferenza del Nobel, che \u00e8 un vero e onesto resoconto dei progressi e della storia dell'argomento, il professore nomina tutti i suoi collaboratori in ordine a partire da K.

V. Raman ha fatto una svolta significativa, ricordiamoci anche che la sua scoperta non \u00e8 stata fatta da una sola persona. \u00c8 stato il prodotto di una collaborazione tra due scienziati, il risultato di due persone che hanno messo insieme le loro teste, le loro capacit\u00e0 e le loro competenze.<\/div>\n<div>\n<div>Mentre celebriamo la Giornata Nazionale della Scienza, ecco altre meravigliose collaborazioni, scoperte e innovazioni!<\/div>\n<p>&nbsp;<\/p>\n<div><\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Eighty nine years ago, an Indian scientist discovered a phenomenon that would change the way the world understood the scattering of light.
