PPT-Waves and Wave Properties

Why are we able to see Answer Because there is light Andwhat is light Answer Light is a wave Sowhat is a wave Answer A wave is a disturbance that carries energy from place to place . 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. T. ypes of wave interactions. Reflection. Refraction. Diffraction. Interference. Reflection. The bouncing back of a wave when it hits a surface.. * NOTE: When waves hits a substance some of it is transmitted and some of it is reflected.. 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.. A Physics MOSAIC. MIT Haystack Observatory RET. Revised 2011. Background Image from Wikipedia, Roger . McLassus. , Creative Commons . Reflection. When a wave encounters a boundary, it will be. at least partially reflected off this boundary.. REMINDER!.

Crest . – . the highest part of a transverse wave.. Leonardo de Vinci. Waves Properties. 1. Transverse Waves:. The particles of the medium vibrate perpendicularly to the direction of the 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. A wave is a vibration. That travels from place to place. Thus it is two motions each with its own direction. The . Vibration. : a SHM. The . Propagation. ; its motion from place to place. Together they from a wave. Looking back, it may seem odd that two decades passed between the 1905. discovery of the particle properties of waves and the 1924 speculation that particles might show wave behavior. It is one thing, however, to suggest a revolutionary concept to explain otherwise mysterious data and quite another to suggest an equally revolutionary concept without a strong experimental mandate. The latter is just what Louis de Broglie did in 1924 when he proposed that moving objects have wave as well as particle characteristics. So different was the scientific climate at the time from that around the turn of the century that de Broglie’s ideas soon received respectful attention, whereas the earlier quantum theory of light of Planck and Einstein had been largely ignored despite its striking empirical support. The existence of de Broglie waves was experimentally demonstrated by 1927, and the duality principle they represent provided the starting point for Schrödinger’s successful development of quantum mechanics in the previous year. 2022-2023 Season.
