What is a Medium?
But what is meant by the word medium? A
medium is a substance or material that carries the wave. You have perhaps heard of the phrase
news media. The news media refers to the various institutions (newspaper offices, television stations, radio stations, etc.) within our society that carry the news from one location to another. The news
moves through the media. The media doesn't make the news and the media isn't the same as the news. The news media is merely the
thing that carries the news from its source to various locations. In a similar manner, a wave medium is the substance that carries a wave (or disturbance) from one location to another. The wave medium is not the wave and it doesn't make the wave; it merely carries or transports the wave from its source to other locations.
