In the last fifteen minutes we learned about UNIT 10!!! Unit 10 is about electromagnetic waves and light behaviors. Electromagnetic waves are transverse waves, but they are different than sound waves. Electromagnetic waves travel at the speed of light, which is 3x10^3 meters per second. Electromagnetic has two parts to the word, electric and magnetic. Electric is the wave that has the motion going up and down. Magnetic has the motion that goes side to side. Therefore, electromagnetic waves are waves that go up and down and side to side at the same time.
There are also transparent and opaque waves. Transparent waves are waves that are able to travel through something. Opaque waves are not able to travel through.
In order to see an object, light has to come back to your eyeball.
Deep thoughts:
Light is the only thing we see.
Sound is the only thing we hear.

| Waves in the ocean go side to side and up and down at the same time sometimes, which could sort of be an example of electromagnetic waves. |
