There are many different ways to communicate with others. Speaking face to face is still important, but there are some interesting inventions that have increased humans’ ability to communicate with each other.
Writing letters was one of the first ways people were able to communicate long-distance. This helped maintain the accuracy of the information rather than passing a story from one person to the next to the next. Remember those old games of “Telephone” where the end result was gobbledygook?
With cell phones becoming so common that even children have them nowadays, it may be hard to remember how incredible it was for people to actually speak to each other from a distance. The look of the phone has changed and shrunk, but the initial purpose still holds true.
Radio waves are a part of the electromagnetic spectrum and were proven to exist by Heinrich Hertz. That is why the term Hertz is used to measure radio frequency. With the invention of RF power dividers and splitters, innovators have been able to create many different things that help people communicate with each other.
Radio waves are used to broadcast both radio and television signals. This has brought those with important messages into the living rooms of thousands of people and made both the celebrity and the message recognizable to people all over the world.
When the internet connected people globally, not only by voice but also through video and written messages, it was a breakthrough that has had far-reaching consequences. Through many platforms, people can interact as though they were in the same room from anywhere in the world. It has revolutionized communication.
No matter what tools you use to communicate with others, you have opportunities to do it all the time. The world has come a long way in a relatively short time and people have been brought together from all walks of life.
