What is the primary function of an antenna in a communication system?
Correct Answer: Antenna ka primary function hai electrical signals ko electromagnetic waves mein convert karna aur reception ke liye reverse process karna.
Step 1: Understand that an antenna is a device used in communication systems.
Step 2: Know that antennas are used to send and receive signals.
Step 3: Learn that when sending a signal, the antenna takes electrical signals and converts them into electromagnetic waves.
Step 4: Realize that when receiving a signal, the antenna does the opposite: it takes electromagnetic waves and converts them back into electrical signals.
Step 5: Conclude that the primary function of an antenna is to facilitate communication by converting signals between electrical and electromagnetic forms.
