) Waves emitted from the antenna are:

Explanation

When waves are emitted from an antenna, they are typically radio waves. Let's briefly discuss each option:- A) Sound waves: Antennas are not designed to emit sound waves. Sound waves require a medium (such as air, water, or a solid) for propagation, while antennas operate in the electromagnetic spectrum.- B) Electromagnetic waves: This is a broad category that includes various types of waves. In the con of antennas, the specific type is usually radio waves.- C) Radio waves: Correct. Antennas are commonly used to emit radio waves, which are a type of electromagnetic wave with frequencies in the radio frequency range.- D) Modulated waves: Modulation is a technique used to encode information on a carrier wave. While radio waves can be modulated (for example, amplitude modulation or frequency modulation), the term "modulated waves" is not specific enough to identify the type emitted from an antenna.So, the correct answer is C) Radio waves. Antennas are typically used to emit radio waves in communication systems.
