Official Solution & Explanation:
Correct Answer: Option D(390 - 780 nm के बीच)
दृश्य प्रकाश विद्युत-चुंबकीय स्पेक्ट्रम का वह भाग है जिसे सामान्य मानव नेत्र देख सकते हैं। इसका तरंगदैर्ध्य विस्तार लगभग 390 nm से 780 nm (3900 Å से 7800 Å) तक होता है।
Visible light constitutes the segment of the electromagnetic spectrum detectable by the human eye, spanning approximately from 390 nm to 780 nm (3900 Å to 7800 Å).
