What occurs when a transmitted electromagnetic wave passes through the receiver antenna?

• A. Reception of audio signals
• B. Suppression of noise
• C. Voltage induction in the antenna
• D. Frequency variation

Answer: (C)

When a transmitted electromagnetic wave encounters the receiver antenna, voltage induction occurs in the antenna as a result of the electromagnetic wave interacting with it. This phenomenon is based on the principles of electromagnetic induction, where a changing magnetic field can induce an electromotive force (EMF) in a conductor. As the electromagnetic waves propagate through space, they create an oscillating electric field that interacts with the conductive material of the antenna. This interaction leads to the generation of electrical current or voltage within the antenna. This induced voltage is essential for the antenna to convert the electromagnetic energy into an electrical signal that can be further processed for audio signals or other forms of communication. The induction process is fundamental to how antennas operate in receiving radio, television, and other types of signals, allowing for the transmission of information.
