Explanation:

पूर्ण आन्तरिक परावर्तन एक प्रकाशीय परिघटना है जिसमें प्रकाश की किरण किसी माध्यम के तल पर ऐसे कोण पर आपतित होती है कि उसका परावर्तन उसी माध्यम में हो जाता है। ... प्रकाशीय तन्तुओं का कार्य पूर्ण आन्तरिक परावर्तन के सिद्धान्त पर ही आधारित है।

पूर्ण आंतरिक परावर्तन की परिभाषा

जब कोई प्रकाश की किरण सघन माध्यम से विरल माध्यम में जाती है। तथा आपतन कोण का मान क्रांतिक कोण से अधिक हो जाता है तब विरल माध्यम में प्रकाश की किरण का अपवर्तन नहीं होता है। बल्कि संपूर्ण प्रकाश परावर्तित होकर सघन माध्यम में ही वापस लौट आती है। इस घटना को पूर्ण आंतरिक परावर्तन कहते हैं।
