Okay, so during every moment of our lives, we are struck with waves of energy. Most energy waves collide with us or pass right through us, and we don't even notice. Another big part about waves is matter. Waves carry energy, not matter. But, matter can be used to transfer waves. Let's go over a few vocab words.
Mechanical Waves: Waves that use matter to transfer energy. Water, sound, and earthquake waves are examples.
Medium: The matter used to transport waves. Mediums can either be solid, liquid, or gas.
The Medium here woud be water; This is an example of a mechanical wave.
Electromagnetic waves: Waves that do not require matter to transfer energy are electromagnetic waves. Radio waves, x-rays, microwaves, and visible light waves are examples. They can all travel through empty space and all travel at the same speed, which is sometimes called the speed of light.
Now let's talk about tranverese/ longitudinal (I prefer to call them tuna) or compression waves. Mechanical waves can be classified into either one according to the motion of matter involved, while electromagnetic waves are a special type of transverse wave.
Tuna or Compression waves: Mechanical waves in which medium matter moves forward and backward in the same direction the wave travels.
A slinky is an example of L/C waves
Transverse waves: These can be classified into Mechanical waves, and yet electromagnetic are a special type of transverse. Matter moves up and down or back and forth at right angles, compared to the direction of movement.
Now for a short little story about Leonardo Da Vinci.
Once upon a time, in the fifteenth century, Da Vinci was sitting in his office, and he observed an observation about waves. (because that's totally not what this blog is about ;) He observed that while waves move, the medium does not. He then stood up and said "Like the waves made in a field of grain by the wind, where we see the waves running across the field while the grain stays in place." He basically meant that waves move the medium.
Here is a really cool video by the most awesome british guy on youtube, Charlieissocoollike. In this video, he talks about lights, but he also has some pretty cool stuff to say about waves too. And yes, I know, the video sticks out of the frame. That is my blog. Oh well. Live on your lives, people.
Well, that is really it for this blog, and I hope you enjoyed. Below you will find some links. SuperSaraSuperBye!!

So, SuperSara, that was a great blog. It had the information, and it had some really great pictures. I love the video, 'cause that guy is hilarious, but I don't exactly think it had to do with what you were talking about. I know they were talking about sound waves, but that was only a short part of the video. Overall, though it was a great blog as usual, and I loved it, though I was sad to see the smiley go.
ReplyDeleteThank you so much for reminding me of caroloke! I am so happy she is here. As for your other comments, thanks! I really appreciate it feebs
