26 th 2016 Trigger Warning Well talk about tsunamis today Wave Steepness wave height H wavelength L If the wave steepness exceeds 17 the wave breaks Soanytime a wave exceed the 17 ratio it breaks At shore or at sea. Doppler Effect. ~apparent change in frequency of a wave due to the motion of the source 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. 1 . to 2. Defining ‘Coast’ and Waves. Lesson Objectives. 1) Know what is meant by term the ‘coast’.. 2) Understand waves. . Success Criteria. )Define ‘coast’.. 2)Draw an accurate annotated wave diagram.. 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.. Copyright and Terms of Service. Copyright © Texas Education Agency, 2011.

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. 2022-2023 Season. Russ Burleson. geaux15@hotmail.com. . 1. Agenda. Binder Check/Homework review. Mechanical Wave overview. Transverse Waves. Surface Waves. Longitudinal Waves (general). Sound Waves (Longitudinal). - 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. 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.. water. waves.... 4/5/2019. Physics 214 Fall 2010. 2. 1S-13 Slinky on Stand. Creating longitudinal compression waves in a slinky. What happens when you pull back and release one end of the slinky . ? . Chapter 10. Trigger Warning –. We’ll talk about tsunamis today. Roaring 40s. Furious Fifties. Screaming Sixties…. Wave Steepness . = wave height (H)/ wavelength (L). If the wave steepness exceeds 1/7 – the wave breaks!. The Scottish physicist James Clerk Maxwell (1831–1879) was the first person to truly understand the fundamental nature of light. . He proved in 1865 that an electromagnetic disturbance should propagate in free space with a speed equal to that of light..
