PPT-Chapter 14 Sec 3 Waves What You Will Learn

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 youve never been to the seashore youve most likely seen waves on TV . 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.. Section . 1- What . are electromagnetic waves?. WHAT DO CORDLESS PHONES AND MICROWAVE OVENS HAVE IN COMMON?. Each emits electromagnetic waves.. Remember…. A . wave. . is a repeating disturbance or movement that transfers energy through matter or space.. Session S053 . Tennessee B. The Question of the Ages…. Why do we have to know this?. Answer: It makes the jokes funnier. Modern Family, . ABC Television. “Dave Barry: A Journey into My Colon and Yours”. 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. 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. Waves transfer energy!. A wave does not carry matter . It only moves matter as it travels through it.. Waves. Compression (longitudinal) waves . are waves in which the particles of the medium move in a direction . 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.. 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. 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. 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.. S.47 Get 1 full page and 1 half page of paper.

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.
