-waves that require a medium through which to travel
Name two types of mechanical waves.
-transverse and longitudinal
Which type of wave moves in an up and down motion?
What type of wave moves parallel to the wave energy?
Which type of wave contains compressions and rarefactions?
What is a Wave?
-A disturbance that travels from one place to another transporting energy, but not necessarily matter, along with it.
What is a medium?
-It is the material through which a wave travels.
Which type of waves require a medium?
What are 3 types of mediums a mechanical wave can travel through?
-Solids, liquids, and gasses.
Which type of wave does not require a medium?
-A repeated back-and-forth or up-and-down motion.
-Maximum distance a wave varies from its rest position
-The distance from two corresponding (or the same) parts of a wave.
-How many waves can pass a given point per second, measured in Hertz (Hz)
-Highest point of a wave
-Lowest point of a wave.
-Is the ability to do work.
-Is the human perception of sound intensity.
What two factors does loudness depend on?
1. Amount of energy.
2. Distance from the source.
-A change in sound frequency caused by motion of the sound source, motion of the listener, or both.
-A vibration that travels through Earth carrying the energy released during an earthquake.
-The part of a longitudinal wave where the particles of the medium are close together.
-The part of a longitudinal wave where the particles of the medium are farther apart.
Which type of medium does sound travel fastest though?
Why can't sound travel in space?
-Space has no medium for the wave to travel on.
