13-2 sound intensity and resonance Relate sound intensity to amplitude Explain why resonance occurs.
A sound is a wave and frequency determines pitch In your mind what is sound? Sound is an example of a mechanical wave and is produced by a vibrating object.
Interactions of waves
Wave Interactions. Reflection The interaction of a wave with a surface it cannot pass through. The interaction of a wave with a surface it cannot pass.
Resonance, Sound Waves and The Ear .
A standing wave is produced when a wave that is traveling is reflected back upon itself. There are two main parts to a standing wave: Antinodes – Areas.
Ch 20 SOUND Sound is a compression wave in an elastic medium. These can include solids, liquids and gases or a plasma.

Circuits to Optics June 16, 2004. Which type of field is present near a moving electric charge? (A) an electric field, only (B) a magnetic field, only.
ALL sounds are produced by vibrations. Sound waves travel as longitudinal (compressional) waves. Compression – region of high molecular density and.
Sound waves are longitudinal waves. When sound waves occur in air, air molecules press together and push apart. Based on what you know about longitudinal.
