The Importance of Electromagnetic Waves

Now, in the 21st century, electromagnetic waves are a very crucial part of our lives. Even though we are often not aware of how much they actually effect and influence our lives, electromagnetic waves enable easy communication and help us live our lives easier. In the 1860's and 1870's, James Clerk Maxwell who was a scientist from Scotland was the first one to notice that if you put electric and magnetic waves together, they are very powerful- creating electromagnetic waves. Electromagnetic waves are used by cell phones, computers, televisions, and even microwaves. They simplify our lives by letting us connect to people around the globe within second, and creating a whole "global village" that keeps the everyone in the world in touch with what is happening on the other side of them hemisphere. These waves make communication and news-spreading extremely fast and efficient. In the olden times, news took weeks, if not even months to travel, while now, you can send an email and get it delivered within seconds, or call somebody and spread the news right away. Electromagnetic waves also make our home life easier and more luxurious by enabling us to heat our food in microwaves  to heat up food(instead of making a fire) and let us relax and get information from television. Overall, electromagnetic waves have a major effect on our lives, even though we are often not aware of how much we actually rely on them :)
