PPT-Wave Properties Six Interactions of Waves

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. 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. 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. REFLECTION. Reflection. is where a wave strikes an object and bounces off.. When a wave strikes a flat reflective surface it will reflect back at the same angle at which it struck the surface. This is called the Law of Reflection.. 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.. 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). 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. Period Motion. Any . motion that . repeats. at regular time intervals. Frequency. Number . of . complete cycles . in a given . time. Frequency . is measured in . Hertz (Hz). Properties of Mechanical Waves. Why are we able to see?. Answer: . Because there is light.. And…what is light?. Answer: . Light is a wave.. So…what is a wave?. Answer: . A wave is a disturbance that carries energy from place to place. . Get 1 full page and 1 half page of paper. Fold full sheet of paper. about 1-1.5” short of even. Insert half sheet in the middle.

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.. Earthquakes-Tsunamis. Graviational. attraction-Tides. Wind waves move energy, not matter. Wind waves- Growth. Wind strength- must be moving faster than waves. Wind duration-longer creates larger waves.
