National Science Day short speech in Hindi

महान भारतीय भौतिक विज्ञानी सर सी. वी. रमन द्वारा रमन इफेक्ट की खोज को चिह्नित करने के लिए भारत में हर साल 28 फरवरी को राष्ट्रीय विज्ञान दिवस मनाया जाता है। इस दिन 1928 में, सर सी. वी. रमन ने रमन इफेक्ट की खोज की थी। उनकी खोज के लिए, उन्हें वर्ष 1930 में भौतिकी में नोबल पुरस्कार से सम्मानित किया गया था।

सी. वी. रमन जी का पूरा नाम चंद्रशेखर वेंकट रमन है। उनका जन्म 7 नवंबर 1888 को भारत के तमिलनाडु के तिरुचिरापल्ली में हुआ था। वह बचपन से ही बुद्धिमान थे। उन्होंने ब्रिटिश जर्नल में अपना पहला वैज्ञानिक पत्र प्रकाशित किया जब वह 18 वर्ष के थे। उन्होंने 19 साल की उम्र में अपनी एमए की डिग्री पूरी की और उस वर्ष अपना दूसरा वैज्ञानिक पत्र भी प्रकाशित किया।

सी. वी. रमन मुख्य रूप से प्रकाश प्रकीर्णन के क्षेत्र में अपने काम के लिए जाने जाते हैं। उन्होंने पाया था कि जब प्रकाश एक पारदर्शी सामग्री से गुजरता है, तो कुछ विक्षेपित प्रकाश का तरंगदैर्ध्य और आयाम बदल जाता हैं। यह एक पूरी तरह से नई खोज थी और इसे रमन इफेक्ट का नाम दिया गया।
