PPT-The Behavior of Waves Chapter 17:3

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.

If the object is moving towards the observer the frequency will appear to increase. If the object is moving away from the observer the frequency will appear to decrease. 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. . 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.. 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. La gamme de thé MORPHEE vise toute générations recherchant le sommeil paisible tant désiré et non procuré par tout types de médicaments. Essentiellement composé de feuille de morphine, ce thé vous assurera d’un rétablissement digne d’un voyage sur . Warm-Up: February 17/18, 2016. Vibrations and Waves. Chapter 14. A . periodic motion . repeats in a regular cycle.. Examples include:. Pendulums (such as on a grandfather clock). A mass at the end of a spring. Periodic Motion. Motion that repeats in a regular cycle is called . periodic motion. . . The revolution of a planet about its sun is an example of periodic motion. The highly reproducible period (T) of a planet is also called its year.. - Jon . Kabat. -Zinn. Waves are moving . energy. !. Most waves wind-driven. Moving energy along ocean/air interface:. Wind main disturbing force. Boundary between and within fluids with different densities. Earthquakes-Tsunamis. Graviational. attraction-Tides. Wind waves move energy, not matter. Wind waves- Growth. Wind strength- must be moving faster than waves. Wind duration-longer creates larger waves.
