PPT-Waves Chapter 10 Nature of Waves

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. 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.. 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.. 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).. 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. 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 . Motion—Spring . Oscillations. Energy . in Simple Harmonic Motion. The . Period and Sinusoidal Nature of SHM. The . Simple Pendulum. Hooke’s Law. 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. College Physics Chapter 24 ELECTROMAGNETIC WAVES PowerPoint Image Slideshow Figure 24.1 Human eyes detect these orange “sea goldie ” fish swimming over a coral reef in the blue waters of the Gulf of 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.. 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.. Energy is moving, not water. orbital motion. energy is transferred via circular motions. water (and gull) return to original position. the wave form moves forward. Motion decreases with depth. At. a depth of ½ of the wavelength, the motion is not significant..
