Now that we are through with waves, we are moving onto the topic of sound. Sound waves are waves that are . We will go back and talk about the early days of atomic theory soon.. Today, let’s focus on the development of atomic theory in the 1900s and WAVE MECHANICS.. In the late 1800’s, scientists noticed that objects glowed at certain colors when heated to high temperatures…. 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. 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.. 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 .

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. . 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.
