Unit 4: Waves and EM Waves Chapter 3: Electromagnetic Waves Lesson 2: Waves of the Electromagnetic Spectrum Pages 88 - 95 SCCCR Standards 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.

Science and Engineering Practices Unit 4: Waves and EM Waves Chapter 3: Electromagnetic Waves Lesson 2: Waves of the Electromagnetic Spectrum Pages 88 - 95 Science and Engineering Practices 8.S.1A.6 Construct explanations of phenomena using (1) primary or secondary scientific evidence and models, (2) conclusions from scientific investigations, (3) predictions based on observations and measurements, or (4) data communicated in graphs, tables, or diagrams.

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

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

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

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
