How did We Know About Lasers Hindi Book Pdf Download

Short Description Of The Book:

After all, what a wonderful ray of light it is, which can cost the super-market and even heal bad eyes. What kind of a ray of light is this that can even pierce steel and print a delicate photo on paper.

In the 1950s, Max Planck’s quantum theory, Einstein’s new thinking and Charles Towne’s experiments paved the way for this powerful beam of light.

Light normally gets scattered here and there. There was a need to concentrate it in one place. Then to strengthen and straighten by stimulating a particular wavelength. A device was created that could make all this possible thanks to the laser.

How it all happened is a thrilling story. Scientists engaged in the discovery of laser also gained a lot of knowledge about light.

In this book you will come to know about the discovery and amazing use of laser (LASER) which is short form of Light Amplification by Stimulate Emission Of Radiation. What other uses can lasers have — only the future knows……

पुस्तक का संक्षिप्त विवरण:

आखिर प्रकाश की यह कैसी अद्भुत किरण है जो सुपर- मार्केट में वस्तुओं के दाम भी पड़ सकती है और खराब आंखो को ठीक भी कर सकती है। यह प्रकाश की कैसी किरण है जो स्टील में छेद भी कर सकती है और कागज पर नाजुक सी फोटो भी छाप सकती है।

1950 के दशक में मैक्स प्लैंक के क्वांटम सिद्धांत, आइंस्टाइन की नई सोच और चार्ल्स टाउन के प्रयोगों ने प्रकाश की इस शक्तिशाली किरण तक पहुंचने का मार्ग बनाया।

प्रकाश सामान्य रूप से इधर-उधर बिखर जाता है। आवश्यकता थी उसे एक जगह केंद्रित करने की। फिर एक विशेष वेवलेंग्थ को उत्तेजित करके शक्तिशाली और सीधा करने की। एक ऐसे उपकरण की रचना की गई जो यह सब संभव कर सके लेजर के लिए।

यह सब कैसे हुआ एक रोमांचकारी कहानी है। लेजर की खोज में लगे वैज्ञानिकों को प्रकाश के बारे में भी काफी ज्ञान प्राप्त हुआ।

इस पुस्तक में आपको लेजर (LASER) जो की Light Amplification by Stimulate Emission Of Raditation का संक्षिप्त रूप है, की खोज और उसके आश्चर्यजनक उपयोग के बारे में पता लगेगा। लेजर के और क्या उपयोग हो सकते हैं — भविष्य ही जानता है……
