PPT-Chapter 15.1 – Types of Waves

wave disturbance that carries energy through matter or space medium matter through which a wave travels the physical environment in which phenomena occur mechanical wave wave that requires a medium through which to travel. 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.. An-Najah National University.

Waves . *Refer to Chapter . 12 . in your Textbook . Learning Goals. : . I can label the anatomy of an ocean wave.. I can differentiate between the various types of waves.. Anatomy of a Wave. :. Crest. Periodic Motion – any repeated motion with regular time intervals. Simple Harmonic Motion – vibration about an equilibrium position in which a restoring force is proportional to the displacement from equilibrium . 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).. Identify the parts of a wave. . • Explain how the parts of a wave relate to wave movement. . • Describe how ocean waves form and move. . • Classify types of waves. . Have you seen a wave? . We all know what ocean waves look like. Even if you’ve never been to the seashore, you’ve most likely seen waves on TV. . © 2014 Pearson Education, Inc.. Contents of Chapter 11. Simple Harmonic .

When a spring is stretched, a restoring force is created.. The restoring force is proportional to the displacement . The restoring force is always directed toward the equilibrium point. Section 1. Objectives. 1. Explain the relationship among waves, energy, and matter. 2. Describe the difference between transverse waves and compressional waves. A. Waves Carry Energy. Waves (rhythmic disturbances that carry energy without carrying matter) can carry energy by itself or with matter. These terms must be included in your foldable for home work. Seismology. Deformation. Elastic rebound. Seismic waves. P waves. S waves. What are Earthquakes?. The shaking or trembling caused by the sudden release of energy. 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.. Wave. Repeating disturbance or movement. Carries energy through matter and space. Vibrations. Anything that moves in a rhythmic patter. Up and down. Back and forth. What is a Wave. All waves are produced when something vibrates. A wave is a vibration. That travels from place to place. Thus it is two motions each with its own direction. The . Vibration. : a SHM. The . Propagation. ; its motion from place to place. Together they from a wave. Science Journal Entry 34. Compare and contrast transverse waves, longitudinal waves, and surface waves.. Review. There are three types of waves: transverse, longitudinal, and surface waves.. A transverse wave causes the medium to vibrate at right angles to the direction of the wave. Longitudinal waves (also called compressional waves) cause the medium to move parallel to the direction of the wave..
