8.P.3: The student will demonstrate an understanding of the properties and behaviors of waves
8.P.3A. Waves (including sound and seismic waves, waves on water, and light waves) have energy and transfer energy when they interact with matter. Waves are a repeating pattern of motion that transfers energy from place to place without overall displacement of matter. All types of waves have some features in common. When waves interact, they superimpose upon or interfere with each other resulting in changes to the amplitude. Major modern technologies are based on waves and their interactions with matter.
8.P.3A.1 Construct explanations of the relationship between matter and energy based on the characteristics of mechanical and light waves.

5. Vocabulary
Electromagnetic spectrum
The complete range of electromagnetic waves placed in order of increasing frequency
Radio waves
Electromagnetic waves with the longest wavelengths and the lowest frequencies
Microwaves
Electromagnetic waves that have shorter wavelengths and higher frequencies than radio waves

6. Vocaabulary
Radar
A system that uses reflected radio waves to detect objects and measure their distance and speed
Infrared rays
EM waves with shorter wavelengths and higher frequencies than microwaves
Thermogram
An image that shows regions of different temperatures in different colors

7. Vocaabulary
Visible light
EM radiation that can be seen with the unaided eye
Ultraviolet rays
(radiation) EM waves with wavelengths that are shorter than visible light but longer than x-rays
X-rays
EM waves with wavelengths shorter than ultraviolet rays but longer than gamma rays
Gamma rays
EM waves with the shortest wavelengths and highest frequencies

8. What makes up the EM Spectrum?
How do EM waves compare?
All EM waves travel the same speed in a vacuum, but they have different wavelengths and frequencies
As wavelength decreases, frequency increases.
What makes up the EM Spectrum?
Radio waves – Microwaves – Infrared rays – Visible Light – UV rays – X-rays – Gamma rays
