Reflection A wave is reflected when it comes into contact with a barrier A wave is reflected when it comes into contact with a barrier Law of Reflection.

SOUND Sound is energy transferred by the compression & rarefaction of matter: sound waves are compressional waves Collisions between molecules transfer.

Sound. Speed of sound in solids, liquids, and gases Speed of sound in gas (air): 344 m/sec. Speed of sound in liquid (water): 1100 m/sec Speed of sound.

Sound Waves Three things to know about sound waves: 1)There must be a source for a sound wave, that source will be a vibrating object. 2)The energy transferred.

CHAPTER 12: SOUND Sound is a longitudinal wave. Sound comes from a source, travels in a medium, as longitudinal waves, and is sensed by our ear.

Chapter Review Game. Amplitude: tells us how much energy a wave has.

Periodic Motion Common Example: Pendulum Some elements of periodic motion we can describe –Oscillation or Cycle –Period, T –Frequency, f –Amplitude, A.

Waves and Sounds Ch. 18 Frequency and Pitch  A pitch is the highness or lowness of a sound.  The pitch you hear depends on the frequency of the sound.

Sound Waves Sound A form of energy that causes molecules of a medium to vibrate back and forth in a series of compressions and rarefactions as a longitudinal.

SOUND Sounds are a form of energy produced by rapidly vibrating objects. Sound needs a material medium for its transmission. Sound cannot travel through.

Sound. The origin of sound All sound are produced by the vibrations of material objects. Our voice results from the vibration of our vocal chords. Sound.

1. Frequency times wavelength equals_________. Speed 2. Then number of complete wave cycles per unit time is called? Frequency 3. A ____________ is a region.

What is sound? Sound is a longitudinal wave which travels through the air through a series of compressions and rarefactions.

Intro to waves. The source of all waves is something that vibrates Wave Description.

Characteristics of waves.. The Nature of Waves What is a wave? A wave is a repeating disturbance or movement that transfers energy through matter or space.
