PPT-Waves What is a Wave? Longitudinal Wave

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 waves motion . 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. A disturbance that . propagates.  energy transferred. Examples. Waves on the surface of water. Sound waves in air. Electromagnetic waves. Seismic waves through the earth. Electromagnetic waves can propagate through a vacuum. 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. 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.. MIT Haystack Observatory RET. Revised 2011. MOSAIC Background. MOSAIC stands for Mesospheric Ozone System for Atmospheric Investigations in the Classroom. . It is a method by which the level of ozone in the mesosphere (the layer above the troposphere and the stratosphere) can be measured.. Basic Properties of Waves. Amplitude. Wavelength. Frequency. Speed. Amplitude. Amplitude is the maximum distance the particles of the medium carrying the wave move away from their rest positions.. The farther the medium moves as it vibrates the larger the amplitude of the resulting waves. The greater the amplitude the greater the amount of energy. How do matter and energy interact when waves are generated?. What are the three main types of mechanical waves?. What are properties of waves?. Essential Questions:. Waves. A disturbance that transfers energy from place to place. REMINDER!. DON’T FORGET. TO . STUDY!. . Electromagnetic waves. Mechanical waves. Interference. Reflection. Refraction. Pitch. diagrams. 1. Define . the following words:. Crest . – . the highest part of a transverse wave.. 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. 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. amplitude, frequency, wavelength, speed, phase, phase difference, . c . = . f . λ. . f . = . 1/. T . Phase difference may be measured as angles (radians and degrees) or as fractions of a cycle. . . - 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..
