PPT-Waves….. “You can't stop the waves, but you can learn to surf.”

Jon Kabat Zinn Waves are moving energy Most waves winddriven Moving energy along oceanair interface Wind main disturbing force Boundary between and within fluids with different densities. videos. Science of Big Waves . (KQED). Garrett McNamara . w/ . GoPro. , 90’+. Teahupoo. raw. 2013 . The energy of a wave travels ahead but the water itself does not. Why are there consistently bigger waves in the Pacific?. 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. 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. . 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 . RADIO WAVES. HOW DO RADIO WAVES HELP ASTRONOMERS. Astronomers learn about a stars composition, structure and motion . MICROWAVES. HOW DO ASTRONOMERS USE MICROWAVES. ASTRONOMERS PICK UP THE COSMIC MICROWAVE BACKGROUND THAT WAS LEFT OVER FROM THE BIG BANG. 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.

Insert half sheet in the middle. Staple . across . the fold. Pick up the top two pages and starting from the bottom, cut the top two . 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.. 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 . ? . 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..
