UNEDUCATED PARAGRAPH
You know when you're outside holding sunglasses, a piece of glass, a mirror, etc., and it makes these little rainbow patterns? The light looks like a rainbow..? That's what I think the electromagnetic spectrum. It may be some kind of...list or... pattern... or graph or... whatever. But anyways, this "list pattern graph whatever" shows the light your eyes are able to see? Maybe? I don't know. So that was my uneducated paragraph. Hope you enjoyed.
Okay, so here's the legitimate definition of the electromagnetic spectrum.
Electromagnetic Spectrum: The entire range of electromagnetic waves with different frequencies and wavelengths.
I just think of ES as a bunch of types of radiation, organized by amount of energy. Now you may ask what radiation is. It's basically just any movement of energy of through energy. Now there are many properties of the ES. Let's go over them!
Radio Waves: About the weakest wave on the ES. These are categorized into three different waves: AM, FM, and television waves. TV is high frequency, FM is medium, and AM is low.
Hehe... I made this one ^
Microwaves: Used in airplanes and microwaves. Pretty simple. Microwaves actually use microwaves! They do this by releasing radiation into the particles in your food, that cause them to move and create heat! Thus making your food warm! Yum!
Infrared Waves: These are often produced when an object radiates heat. You can't see it, but you can feel it. These are used in remotes.
Ultraviolet Waves: UV waves naturally occur in sunlight and in large doses can give you skin cancer and cataracts (blindness). Make sure to wear your sunscreen!
X-Rays: These waves have high penetrating power. They're used for x-rays, obviously, and can travel through anything. These can be really dangerous if you're not careful.
Gamma Rays: These are are the most powerful rays on the electromagnetic spectrum. These are used in NUCLEAR BOMBS and are absorbed by our atmosphere.
Okay well those are the terms... Here are some random facts about the ES!
- Waves on the ES are organized by how much energy they carry. (Which is really how short the wavelength is, which is really just the frequency)
- SONAR uses microwaves
- If the ozone layer did not block the sun's UV rays, rates of cancer would skyrocket.
- Thermographs are those cool heat pictures :)
Okay guys well that's it! SuperSaraSuperBye!!!!
