What did you first think of when you read the word "WAVE" in the title of this blog posting? That word has a lot of different meaning. I first thought of radio waves, since I am an amateur radio operator, but that is only one kind. I would also wave at you when I see you
Waves can be defined by what medium they travel through. The two basic waves are mechanical and electromagnetic. When you throw a stone into the still waters of a pond, that ring of waves that are produced are mechanical. Mechanical waves need some sort of medium to travel through, whether it be liquid or solid. Electromagnetic waves do not need any media to travel through. That is why they can travel through space and we can converse with the astronauts on the moon.
Without ocean waves what would the surfers do? Without ladies wanting waves in their hair, beauticians and hair stylists would have nothing to do. Without audio waves we would have trouble talking to each other. Without electronic waves I couldn't write this blob on my computer nor could I post it on the internet where you can access it through waves and then read it on your computer. OK, now I will wave goodbye and hope you all have a great day, you hear?
