Which of the following is an/a audio/ visual means of communication?a)...
Answer:
The correct answer is option 'A' - Television.
Explanation:
Audio/visual means of communication refers to modes of communication that involve both sound and visual elements. These modes allow individuals to both see and hear the message being communicated. Among the options given, television is the only medium that provides audio and visual components simultaneously.
Television:
Television is a device that receives broadcast signals and displays them on a screen. It combines audio and visual elements to convey information, entertainment, and various forms of media. Television programs consist of moving images, accompanied by sound, which allows for a complete audio/visual experience. This makes television a powerful medium for communication, as it can effectively convey messages to a wide audience.
Other Options:
Although the other options mentioned, such as letter and radio, are means of communication, they do not fulfill the criteria of audio/visual communication:
Letter:A letter is a written form of communication that involves only the visual element. It is a message conveyed through written words on a piece of paper or other mediums. While letters can be read aloud to provide an audio component, they are primarily considered a visual means of communication.
Radio:Radio is a medium that primarily relies on sound to convey messages. It does not provide a visual component unless accompanied by additional visual aids, such as online streaming platforms that display images or videos alongside the audio. However, traditional radio broadcasts do not offer a visual element and are therefore not considered an audio/visual means of communication.
Conclusion:
Among the given options, television is the only medium that combines both audio and visual elements, making it an audio/visual means of communication. It provides a complete audio/visual experience, making it a powerful tool for conveying information and entertainment to a wide audience.
