Download Solution PDFसही विकल्प 3 है।
अवधारणा:
विकिरण का कोण क्षैतिज एन्टेना के सबसे निचले भाग 'θ' का उन्नयन कोण है जो तरंगदैर्ध्य 'h' के सन्दर्भ में एन्टेना की ऊंचाई से \(\theta = {\sin ^{ - 1}}\left( {\frac{{0.25}}{h}} \right)\) से सम्बंधित है।
अत: ऊंचाई में वृध्दि से साइन के व्युत्क्रम फलन के मान में कमी होती है, इसलिए θ का मान घटता है।Last updated on Jul 17, 2025
