PPT-Waves Objectives: Wave Motion

Interference of Waves Standing Waves Tsunamis Waves Frequency Wavelength Velocity Wave Motion A vibrating point drags its neighbours into motion As the motion spreads through space a wave forms. Aaron Bunch. Abstract. The example of seismic waves in earthquakes leads us to expect that longitudinal and transverse waves will have different wave speeds in . a Slinky. . Using video analysis software, the speeds of longitudinal and transverse waves were measured in . 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. Typically, harmonic motion decreases in amplitude with time….this realistic model describes damped harmonic motion.. The damping effect is a result of friction and internal resistance of the system to further motion.. Wave Properties. There are 6 main properties, or interactions, of waves that occur when a wave comes in contact with another wave , or a boundary. . The 6 Interactions of waves are. Interference. Diffraction. 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. Explain how force, velocity, and acceleration change as an object vibrates with simple harmonic motion.. Calculate the spring force using Hooke’s law.. OBJECTIVES. What is periodic motion?. A repeated motion (e.g. pendulum swinging) that is back and forth over the same path.. 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.. A wave is any disturbance that transmits energy through matter or empty space.. Energy can be carried away from it’s source by a wave. As a wave travels, it does work on everything in it’s path. 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). 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 . ? .
