20222023 Season Russ Burleson geaux15hotmailcom 1 Agenda Binder CheckHomework review Mechanical Wave overview Transverse Waves Surface Waves Longitudinal Waves general Sound Waves Longitudinal. S8P4. Students will explore the wave nature of sound and electromagnetic radiation. . a. Identify the characteristics of electromagnetic and mechanical waves. . What are waves?. Waves carry energy. Rhythmic disturbances that carry energy without carrying matter are called waves.. Section 1: What are Waves. SWBAT: . Explain . the relationship among waves, energy and matter. Science Starter. 1. Name . 3-5 types of . waves.. 2. What . do you think creates waves on the ocean?. When you are relaxing on an air mattress in a pool and someone does a cannonball dive off the diving board, you suddenly find yourself bobbing up and down.. Waves. Ch. 20 Sec. . 1 & 2. The Nature of . Waves & Properties of Waves. Waves. We often associate waves with bodies of water, but are there other situations where waves can exist?. Waves. wave. What is a wave?. A wave is a repeating disturbance or movement that transfers energy through matter or space. Waves transfer energy not matter. The water waves below are carrying energy but are not moving. Waves can only exist as they have energy to carry.. Presentation Outline. Mechanical waves are particle-to-particle interactions. Slinky Demonstration. Medium definition. Wave speed. Sound Wave in a Medium. Production of Sound Waves. Compressions and Rarefactions. Sound. © 2016 Pearson Education, Inc.. Goals for Chapter 12. To describe mechanical waves.. To study superposition, standing waves and sound.. To present sound as a standing longitudinal wave.. To see that waves will interfere (add constructively and destructively).. Wave Properties. There are 6 main properties, or interactions, of waves that occur when a wave comes in contact with another wave , or a boundary. . The 6 Interactions of waves are. Interference. Diffraction. S8P4b. Describe how the behavior of light waves is manipulated causing reflection, refraction, diffraction, and absorption.. Reflection. Reflection occurs when a wave strikes an object or surface and bounces off.. Producing and Detecting sound. What is sound?. The sound you hear is sound waves that can only travel through matter.. Sound waves are longitudinal waves. . Sources of sound. Every sound comes from a vibration, which is the energy that the wave uses to carry the sound.. REMINDER!. DON’T FORGET. TO . STUDY!. . Electromagnetic waves. Mechanical waves. Interference. Reflection. Refraction. Pitch. diagrams. 1. Define . the following words:. Crest . – . the highest part of a transverse wave.. Before the waves are made the particles are same distance apart. While waves moves through the medium the particles . compress. together, then they spread further apart (stretched areas)- . rarefaction.. Mechanical Waves. A mechanical wave is created when a source of energy causes a vibration to travel through a medium.. A mechanical wave is a disturbance in matter that carries energy from one place to another.. difference between mechanical waves and electromagnetic waves. . What is a wave?. A wave is a moving disturbance that transfers energy through matter or space. . Examples of waves. Water waves light waves. a. Identify the characteristics of electromagnetic and mechanical waves. . What are waves?. Waves carry energy. Rhythmic disturbances that carry energy without carrying matter are called waves.. Models of Waves.
