and OMG! this wasnt a pun! we are actually going to be refrencing actual waves!!!!
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
now lets get to the important stuff. What is a wave Madeline? Well a wave transfers energy from one place to another. Some kinds of waves need to travel through a medium, and some can travel in space.
a medium is any kind of matter that can be disturbed by energy. Basically- some waves need matter to exist. Like sound waves. They need to travel through oxygen. So thats why sound doesnt travel in space- thers no oxygen.
so you may be wondering about actual waves at the moment. And let me tell you, waves dont actually move. its just energy traveling through them. sort of......
TYPES OF WAVES
There are ocean waves, but were are gonna talk about other kinds of waves. Mehancical and Electromagnetic waves to be exact.
An electromagnetic wave is a wave that is capable of transmitting its energy through a vacuum (i.e., empty space). Electromagnetic waves are produced by the vibration of charged particles. Electromagnetic waves that are produced on the sun subsequently travel to Earth through the vacuum of outer space.
A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum.
Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist.
in the catagory of Electromagnetic, there is Transverse and Compressional waves.
A transverse wave is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves.
A Compressional waves create sound waves by moving the molecules in the air, which in turn creates waves of noise. The more vibrations there are, the louder the sound is.
PARTS OF A WAVE
Once again, theres more to the picture. Im just going to show you what a wave looks like and show you the parts of a wave!! Calm down.....
So first im going to tell you the vocab then show you a picture all together.
The top of a wave is called the CREST
The bottom of a wave is called the TROUGH
The middle of a wave is called the AMPLITUDE
How you measure the amount of energy or the size of the wave is measured from crest to crest. or trough to trough. That is called the WAVELENGHT
Then there is frequency.
if you have a high frequency, then you have a a higher wave with shorter wavelengths.
if you have a low frequency, then you have a lower wave with a longer wavelenghts.

so thats it for this week!! i hope you liked it and i hope you enjoyed it. I had fun making it soooo ya.
pictures are just a Ctr-Click away!
it wasnt my best blog but
oh whale
