What does sound travel through?
Solids, Liquids, and Gases
What does sound not travel through?
What causes sound?
What does one complete wavelength look like?
What does a wave with a low pitch look like?
What does a wave with a high pitch look like?
What is the top of a wavelength called?
What is the bottom of a wavelength called?
How do we measure wavelengths?
From Crest to Crest
Why does sound travel faster along a metal fence than a swimming pool?
The molecules are closer together in a solid
How is the sound you hear underwater different from the sound you hear in air?
The sound underwater travels faster than in the air
What is the number of times a sound vibrates in one second called?
What is the highness or lowness of a sound called?
What is the relationship between pitch and frequency?
The greater the frequency, the higher the pitch
What pitch do shorter strings produce?
High (they vibrate faster)
What pitch do longer strings produce?
Low (they vibrate slower)
What do animals use to help detect objects?
Why can’t people hear some sounds that animals can?
The pitch is either too high or too low
What device is used to detect objects moving through air or space?
What type of device is used to locate objects moving underwater?
Learning Goals: Define wavelength, frequency, period, and amplitude. Describe the relationship between frequency and wavelength. Explain how a wave’s energy.
Sound is a form of energy. It comes from a vibrating source. Sound travels in invisible waves. Sound can travel through solids, liquids, and gases. Click.
How Sound Travels Sound is a mechanical wave It moves by vibrating particles in: –Solids –Liquids –Gases Sound can not travel in a vacuum (empty space)!!!
Sound is a form of energy that is created by vibrations passing through matter. Click Above for Video Clip.
Sound Waves. What is Sound? Sound is caused by a vibration of atoms in pulses. Each sound wave pulses with a certain frequency. The vibration pulse causes.
WAVE UNIT: SECTION 2 NOTES Characteristics of Waves.
- Sound. Sound is a form of energy that travels through matter as waves.
WAVES PROPERTIES Chapter 11, Section 3. What is a wave? A wave is a disturbance that carries energy through matter or space.
Ch Characteristics of Waves
In the margin at the top of the page, list as many things as you can think of that make sound. Share with your partner.
Chapter 15.2 – Characteristics of Waves amplitude – the maximum distance that the particles of a wave’s medium vibrate from their rest position -in a transverse.
Waves © 2006 Certiport.com. Waves Waves are rhythmic disturbances that carry energy without carrying matter.
Sound Overview The Facts of Sound The Ear and Sound Sound Vocabulary Musical Instruments and Sound.
Sound SOL 5.2. What is Sound? Sound is a form of energy that is produced and transmitted by vibrating matter as it moves backwards and forwards. They.
Parts of waves. 2 Parts Transverse Wave 1) Crest – high point of wave 2) Trough – low point of wave.
Physics of Sound WAVES. Sound is a wave. It is a wave of energy that moves through matter; solids, liquids, gases.
Sound and Wave Interactions. Sound “If a tree falls in a forest …?” What is sound? –Longitudinal wave, particles transfer energy –Mechanical wave, must.
Chapter 12-1 Sound Waves. A sound is a vibration. The vibrating causes the air molecules near the movement to be forced closer. This is called compression.
SOUND. Georgia Performance Standards S4P2: Students will demonstrate how sound is produced by vibrating objects and how sound can be varied by changing.
