Electromagnetic spectrum

EM spectrumvised By: Philip Ronan, Gringer

Summary: The electromagnetic spectrum is where all light in the universe falls into, things like radio waves, and gamma rays are some examples of what falls on the spectrum. Even though we can't see most of the light on the electromagnetic spectrum, we have found ways to measure it, both analog and digital, so that we can visualize it to better study all of the different types of light. Only one part of the spectrum can be seen by the human eye, this is called the visible spectrum, which includes all of the colors of the rainbow, and is its own spectrum.

SP4: Analyzing and interpreting data
We took a look at a single graph that was incredibly smooth, and had to plot out ten points that all fell on whole numbers, we then repeated the process but we had to plot out 20 points and they could be whole or fall on half numbers. We observed that as the more points were added to the graph, it not only got smoother, but it also got more accurate to the original graph that we were basing it off of, which shows how accurate results can be given by human hand. 

XCC: Patterns
On the electromagnetic spectrum you can see that the shorter the wavelengths get not only do the waves get warmer and warmer, the frequency also increases. The smaller the frequency is the warmer the color it is represented by is, with one noticeable change of color right where the visible spectrum is, this also correlates to the warmer the wave is at its max power, than the cooler the color its represented by on the spectrum. Meaning that the smallest thing on the spectrum, gamma rays, would have a very light purple representing its frequency and a temperature of about 10,000,000 K.

Summary: Various different types of waves can affect the world in different ways. Like how sound waves can make things audible to the human ear, or how seismic waves can make the ground shake greatly. Even though you can't see them, this applies to electromagnetic waves as well, like how a UV ray can cause a person to get a sunburn, or how X-rays allow us to see inside of our own bodies. Almost, if not all waves can effect the world or the things on it in various ways.


Backward-Looking
In school I personally learned about sounds and waves beforehand, but did not know as much on the topic as I would have liked, meaning that I learned a lot about the topic by working on the project. Specifically things like: the different ways to measure the wavelength and amplitude of different kinds of waves. I gained a lot of knowledge by working on the project.

Inward-Looking
The thing I like the most about this project is the fact that it is flowing with creativity, showing how my team and I can take a task as simple as creating an instrument and making something incredible out of it. The one thing I dislike about the project is that some of the decorations on the instrument itself are lack luster, specifically the 'ears' on the side of the instrument look really bad and poorly done.

Outward-Looking
If I were to give this project a grade I would give it a A, because the project can play any note at a variety of pitches, and not to mention it doesn't take any real skill to play, along with its uniqueness. We made and incredibly interesting design for our instrument, and decided to go with a design that was simple but also really cool. While some parts of the instrument don't look that good, it mostly does as all of the other pieces of the instrument are cool references.

Forward-Looking
The one goal I would like to set for next time is:

When designing a unique solution to a problem, and my team and I hit a roadblock, than rather than doing a small and boring fix, we make it so that the solution fits into the project really well. I say that this is my goal because in our project we came to the roadblock of the sound not being very audible. So we came up with a quick fix to our problem, which was cutting holes in the side. I wish we came up with a greater solution next time.

Sound

Audio Database By: Aarkentechnologies 

Summary: Sound is a mechanical wave that allows us to hear various noises. Sound is a longitudinal wave meaning instead of going up and down, it compresses, and decompresses. Sound is also a type of energy, meaning that it can be used to manipulate matter, different sounds exist because of the fact that they manipulate the air around it. The frequency of the wave is directly related to the pitch of the sound, meaning that the louder the sound, the larger the frequency.

SP5: Using mathematics and computational thinking
We had to use various different types of math to find out about different properties of a wave. We had to do various measurements on things like the distances between two troughs, and the distance from a trough to the top of the wave. We used these measurements to figure out things about the wave, like its frequency, its wavelength, and the amplitude of the waves we measured.

Energy and Matter
Sound relates to energy and matter, because sound itself is a form of energy, you can use sound and the vibrations that it creates to manipulate matter. Matter is also related to sound because it is a mechanical wave, meaning that it cannot exist without matter, because it has to travel through matter to exist, specifically travelling through matter in the form of vibrations.

Waves

2 fixas By: Felipe Tomazoni

Summary: A wave is how various things in the universe move, it's the type of form that something takes. There are two basic types of wave: Electromagnetic, and Mechanical, with the main difference between them being how Mechanical waves need a medium, or matter to move, however an Electromagnetic wave can move through nothingness, also known as vacuum. Then there are two more sub types of waves, Transverse, and Longitudinal waves, which have to do with how the wave moves. A transversal wave goes up and down in humps and troughs, while a longitudinal wave compresses at different parts.

SP3: Planning and carrying out investigations
In order to figure out how sound moves and reacts to different states of matter, we did a lab that involved hitting tuning forks against a table and touching it to different things to see how the items would react. During the investigation, we found that the vibrating tuning fork would make water jump, and when a ball on a string would touch it, the ball would bounce away, no matter how softly we touched it with the vibrating fork.

XCC: Energy and Matter

Lots of different forms of energy travel as waves, such as sound energy, which travels as a longitudinal wave. Matter is needed for the existence of mechanical waves, which need a matter as a medium that they can pass through. Sound is a prime example of this as it can only travel through matter and cannot exist in a vacuum, and it is a type of energy, meaning that energy and matter are incredibly important to the existence of waves. 

What effect can very loud music have on your hearing?

Anatomy of the Human Ear By: Dan Pickard

When loud noises enter your ear they are quite violent vibrations entering your ear, which can cause a variety of problems. When entering your eardrum, the violent vibrations of sound can cause your eardrum to shake so violently that it can rip or break, which can be as bad to cause a person to go deaf. If the violent noise makes it to the cochlea, it can cause the hair cells on the inside to shake violently, which can cause the tips to break off, which means they will constantly be emitting electric pulses to your brain confusing it on whether you're supposed to be hearing something or not, making a ringing noise in your ear, which can last from 1 day to the rest of your life. While some loud noises are okay, others will cause damage to your ear that may be permanent and life hindering.
