Sound E1
A vibration that propagates as an acoustic wave through a transmission medium such as gas, liquid, or solid.
What is Sound?
One periodic event occurring per second.
What are Hertz ?
A tiny packet or "pixel" of light energy
What is a Photon?
The range of light humans can see.
What is the Visible Spectrum?
a wave of compression and rarefaction by which sound is propagated in an elastic medium such as air.
What is a Sound Wave?
the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone
What is the Pitch?
A wave made of electric and magnetic fields that carries energy.
What is an Electromagnetic Wave?
How fast light travels in a vacuum.
What is the Speed of Light?
a sound or series of sounds caused by the reflection of sound waves from a surface back to the listener
What is an Echo?
the manner in which a person behaves, especially in a particular place or situation. OR are materials that allow sound waves to travel through them.
What is a Conduct?
Light bouncing off a surface.
What is Reflection?
The distance between two identical points on a wave; determines color.
What is Wavelength?
is the speed of sound in a specific medium, typically air, representing the point where an object travels at the same velocity as sound waves. This sound travels at 760 mph.
What is Mach1?
The quality of a sound that makes it sound different from other sounds.
What is Timbre?
When light energy is taken in by a material.
What is Absorption?
the particles move back and forth in the same direction as the wave. As the wave moves, it creates areas of compression.
What are longitudinal waves?
sound waves with frequencies below the lower limit of human audibility.
What is Infrasound?
the study of how living things use sound.
What is Bioacoustics?
Bending of light as it moves between materials.
What is Refraction?
the particles of the medium move up and down, while the wave itself moves forward. This movement is at a right angle to the direction of the wave’s travel.
What is transverse waves?
