Which part of the eye is responsible for converting light into electrical signals?
कौन सा भाग आँख का प्रकाश को विद्युत् संकेतों (electrical signals) में बदलने के लिए जिम्मेदार है?
Detailed Solution & Logic
Retina/ रेटिना
Explanation / व्याख्या:
The retina is the innermost layer of the eye that contains light-sensitive cells called photoreceptors (rods and cones). These cells detect light and convert it into electrical signals, which are then transmitted to the brain through the optic nerve.
रेटिना आँख की सबसे अंदर की परत है जिसमें प्रकाश-संवेदनशील कोशिकाएँ होती हैं, जिन्हें फोटोरिसेप्टर्स (रॉड्स और कोन्स) कहा जाता है। ये कोशिकाएँ प्रकाश को महसूस करती हैं और उसे विद्युत् संकेतों में बदलती हैं, जो ऑप्टिक नर्व के माध्यम से मस्तिष्क तक पहुँचते हैं।
Extra Facts / अतिरिक्त तथ्य:
Rods detect dim light and help in night vision, while cones detect colors.
रॉड्स कम रोशनी में दृष्टि के लिए जिम्मेदार होते हैं, जबकि कोन्स रंगों को पहचानते हैं।Damage to the retina can lead to vision loss or blindness.
रेटिना को नुकसान पहुँचने पर दृष्टि क्षीण या अंधापन हो सकता है।The human retina has about 120 million rods and 6 million cones.
मानव रेटिना में लगभग 120 मिलियन रॉड्स और 6 मिलियन कोन्स होते हैं।
