Scientific Waves

Spencer Harrison

Hi, I am Spencer and I am the person who has wrote this blogpost. If you are wondering what this blog post will be about then I am about to explain. This piece of writing will be about waves. Not the ones that you find at the sea though the ones that are involved in science. I will explain what types of waves there are as well as how we can show them using objects. I will also explain where you can find them (though you can’t see them). Then to finish off I will show you what amplitude is and also what a wavelength is. This post will include lots of images as well as lot of one hundred percent correct information. We hope that you enjoy the presentation and for a starter question do you know how many types of waves there are?

How many types of waves are there?

Did you know? If you got the answer two then you are right as there are transverse waves and then there are longitudinal waves. We will talk about transverse waves first. Transverse waves move at right angles to the same direction of the energy that the energy is being transferred to. The second type of wave is called a longitudinal wave. These waves just travel in a straight line and the energy is built up and then realised in an explosion.

What are the best ways to see the waves?

There are many ways to see both types of waves. There is an expensive science tool called a rubens tube. These can clearly show you how many transverse waves there are and you can also change the amount by the button on the side. The only disadvantage about these are that you will not be able to see the longitudinal waves which is the problem with many machines. This is what a rubens tube looks like:

The next type of equipment we are going to explore is called a slinky. Most people will have heard of them and it is just a big safe sprig. This is amazing to show waves as you will be able to see both types of waves unlike the rubens tube and also the next object we will talk about. There is no fault with a slinky and they are also very cheap so you can go buy one from the shop and go experiment yourself. This is how you show a transverse wave with one.

And this is how you show a longitudinal wave with one.

The last way to show the different types of waves is with a jelly baby wave. You can only see the transverse waves with it and you cant count how many wave have past by as they move so quick though you can clearly see that they are transverse waves and depending on how hard you push the first jelly baby it will go back and forth for a while. Once again, I will show an image of which one would look like.

To finish off the blog post I will explain what a wavelength is and also what amplitude is when we are talking about waves. When we are explaining what a wavelength is it is the distance between two waves. Now I will move on to amplitude. When we are talking about amplitude, were talking about the height of the crest. When we say this, we don’t mean the whole crest we mean form the horizontal line in the middle like shown in the middle bellow.

I will show an image to show you what I mean.

That’s it from me (Spencer Harrison) thankyou for reading my post!!
