Sound Ch Review What’s a wave? What does it transport? Wave is a disturbance traveling through a medium transporting energy from one location.

Like all waves, sound waves are produced by a vibration.  A tuning fork vibrates to produce a sound.  A guitar string vibrates to produce a sound.

Making Sound a longitudinal wave produced when matter vibrates – this in turn, causes the medium in which it is in to vibrate ex: tuning fork (the matter)

Essential Question: How does data collected provide evidence that the amount of energy a wave carries determines the properties of a wave?

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

Sound waves are longitudinal waves Loudness is connected to the amplitude – Larger amplitude means louder sound Pitch is connected to frequency and wavelength.

Tuning Forks Lab Review

Understanding Tuning Forks Greater the Frequency = Higher the Pitch Higher the frequency = the faster it vibrates Highestlowest= 480Hz, 426.7Hz, 384Hz, 341.3Hz, 320Hz, 288Hz. LOUDNESS is not the same as High Pitch

Mediums The space that sound waves moves through. Examples: Air, Helium, Wood, etc. Thin surfaces Sound is louder, but does not vibrate very long. Thick surfaces Sound is quieter, but vibrates for a longer period of time.

Size of tuning fork? Tine: the length of the tuning fork. The lower frequency tuning forks have longer tines while higher frequency forks have shorter tines. Shorter the tuning fork, the faster it vibrates = higher the pitch it will be.

Tuning Forks vs. Water When a vibrating tuning fork is placed in a cup of water, the energy from the fork is transferred into the water. If the fork just touches the water, a small amount of water from the top gains kinetic energy and splashes out. If you dip the fork deeply in the water, the vibrations stop.
