PPT-Chapter 12: Mechanical Waves and

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. 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. http://www.youtube.com/watch?v=JN3BQxSroGs. So what is a wave?. Is it energy?. Is it force?. A . Wave. is a disturbance that . transfers. . energy from one place to another without transferring . matter. . Bellringer. : What is A wave? (define, use Ch.22 in your book to help you). What is an example of a wave?. General definitions of vibrations and waves. Vibration. : in a general sense, anything that switches back and forth, to and fro, side to side, in and out, off and on, loud and soft, or up and down is . 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.. 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.. Period Motion. Any . motion that . repeats. at regular time intervals. Frequency. Number . of . complete cycles . in a given . time. Frequency . is measured in . Hertz (Hz). Properties of Mechanical Waves. A. .
