PPT-waves Waves Wave – a periodic disturbance in a solid, liquid, or gas as energy is transmitted.

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 .

Kinetic energy. Light energy. Chemical energy. Mechanical energy. What is Energy?. “Energy” is defined as the ability to do work. Transverse Wave . Clickers! . What does a wave carry? . Energy . Matter. Particles . Atoms . Mechanical Waves . Electromagnetic Waves . Clickers! . A transverse wave travels _______ to the direction of the wave’s motion. . 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.. Ex. In the ocean, waves travel across but the water only oscillates up and down returning to their original position. . Pulse - a single wave from a disturbance. Ex. Throwing a rock in water (a pulse travels in all directions from the point of contact). 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. - 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 . ? . Gregory L. Vogt, EdD. Center for . Educational Outreach. Baylor College of Medicine. What Is Energy?. Energy is hard to define because it changes form. Energy causes a change in the condition of matter, or state changes (such as burning a candle). Or it also can mean movement (such as a vibration or change in physical location). .
