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. Waves. Ch. 20 Sec. . 1 & 2. The Nature of . Waves & Properties of Waves. Waves. We often associate waves with bodies of water, but are there other situations where waves can exist?. Waves. wave. http://www.youtube.com/watch?v=JN3BQxSroGs. So what is a wave?. Is it energy?. Is it force?. A . Wave. is a disturbance that . transfers. . energy from one place to another without transferring . matter. What is a wave?. A wave is a repeating disturbance or movement that transfers energy through matter or space. Waves transfer energy not matter. The water waves below are carrying energy but are not moving. Waves can only exist as they have energy to carry.. The quick review. Properties shared by All Matter. Mass. Volume. Density. Know what these are!. Matter in Different Materials Can Have Different Properties. characteristics it possesses by itself . (in and of itself). Sound. © 2016 Pearson Education, Inc.. Goals for Chapter 12. To describe mechanical waves.. To study superposition, standing waves and sound.. To present sound as a standing longitudinal wave.. To see that waves will interfere (add constructively and destructively).. 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. 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.. Wave. Repeating disturbance or movement. Carries energy through matter and space. Vibrations. Anything that moves in a rhythmic patter. Up and down. Back and forth. What is a Wave. All waves are produced when something vibrates. 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: .
