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 . What interactions can waves undergo?. Name: ________________ Date: ___________. . 6.P.1.1 Waves: Forces and Motion. EQ: What interactions can waves undergo?. Reflection... head your notes like this!. 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. 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.. thermal equilibrium. The experimental basis of quantum mechanics. The black body problem - Planck’s quantization postulate. The photoelectric effect - Quantization of EM radiation. The Compton effect - Light is a particle. 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. 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 . True or False. 1. A . wave transports energy but not matter.. True or False. 2. As . the frequency of sound waves increases, the wavelength of the sound waves decreases.. True or False. 3. Sound . waves cannot travel through solids. 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.. Leonardo de Vinci. Waves Properties. 1. Transverse Waves:. The particles of the medium vibrate perpendicularly to the direction of the wave. 4 Basic Properties of Waves . Amplitude. Wavelength.

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. 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.
