Wave Behavior. When waves encounter new mediums, barriers, or other waves they can behave in different ways. In physics these behaviors are described using some of the . following terms. .. Reflection. Ms. . Meskie. Ms. Krutty. Check This Out!. Volcanoes. Stations. Station 1. Page 1, question 1: What do you think will happen when water is poured over the “hill”?. Station 2. Page 2, question 9: What will happen when you rub sandpaper over the limestone?. April 8 – April 9. Interference. Can two different objects occupy the . exact. same location at the . exact . same time? . Of course not … but two waves can! . When waves meet, they . superimpose . Two pulses travelling in opposite directions will pass through each other unaffected. While passing, the displacement is simply the sum of the individual displacements. CP 514. SUPERPOSITION OF WAVES. Section 9.1. Key Terms. Interference. Principle of Superposition. Constructive Interference. Destructive Interference. Wave Interference. Remember that waves are the result of particle vibrations.. Particles in a medium are connected by forces.. Mel Lemke. November 18, 2013. Helping Players Grow in the Game. Something to Consider. Players have a fear of failure and are motivated by achievements.. "Players perform better if you give them constructive feedback after a mistake. LEQ: How do constructive forces build up the Earth while destructive forces wear down the Earth?(Q). Destructive Forces. Sometimes the earth’s surface changes . VERY QUICKLY. For Example:. Earthquakes. Contracts. April 19, 2016. Conditions. Express. Constructive. Express conditions. Clear conditional language. “It shall be a condition of buyer’s performance under this contract that buyer obtain suitable financing for the purchase of Owner’s house”. Constructive Forces. A constructive force is on that build up the Earth’s surface.. B. Examples: . Mountain building . Deposition of sediment. Volcanic Eruption. August 2006 brought two new things to the . Constructive Process. Things that happen to the Earth that build it up or make positive changes.. Destructive Process. Things that happen to the Earth that destroy or break down part of it. . Erosion. 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.. Crests. Troughs. S. 1. P. S. 2. Crests. Troughs. S. 1.
