Mechanical Waves and Sound
Chapter 17: Mechanical Waves and Sound
Waves What are waves?.
Chapter 11 Waves. Waves l A wave is a disturbance/oscillation generated from its source and travels over long distances. l A wave transports energy but.
Waves Energy can be transported by transfer of matter. For example by a thrown object. Energy can also be transported by wave motion without the transfer.
How does one differentiate between transverse and longitudinal waves?
Vibrations, Waves, & Sound
When an object moves back and forth, it is called a vibration
Ch. 20 Wave Notes Cool Wave Effect Cool Wave Effect.
Warm-Up: January 30, 2012 Where do we encounter waves? Write down all the examples of waves that you can think of.
Waves. What are waves? Wave: a disturbance that transfers energy from place to place. (Energy from a wave of water can lift a boat.) Medium: –the state.
Describe a Wave. Chapter 14 Waves & Energy Transfer.
Vibrations and Waves Chapter 11.
Waves. The Nature of Waves What is a mechanical wave? A wave is a repeating disturbance or movement that transfers energy through matter or space
Harmonic Motion and Waves Chapter 14. Hooke’s Law If an object vibrates or oscillates back and forth over the same path, each cycle taking the same amount.
What you will learn: You will determine how waves transfer energy You will describe wave reflection and discuss its practical significance.
