Mechanical Waves
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?
-Transverse
What type of wave moves parallel to the wave energy?
-Longitudinal
Which type of wave contains compressions and rarefactions?
-Longitudinal
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?
-Mechanical
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?
-electromagnetic
Vibration
-A repeated back-and-forth or up-and-down motion
Amplitude
-Maximum distance a wave varies from its rest position
Wavelength
-The distance from two corresponding (or the same) parts of a wave.
Frequency
-How many waves can pass a given point per second, measured in Hertz (Hz)
Crest
-Highest point of a wave
Trough
-Lowest point of a wave.
Energy
-Is the ability to do work.
Loudness
-Is the human perception of sound intensity
What two factors does loudness depend on?
1. Amount of energy.
2. Distance from the source.
Doppler Effect
-A change in sound frequency caused by motion of the sound source, motion of the listener, or both.
Seismic Wave
-A vibration that travels through Earth carrying the energy released during an earthquake.
Compression
-The part of a longitudinal wave where the particles of the medium are close together.
Rarefactions
-The part of a longitudinal wave where the particles of the medium are farther apart.
Which type of medium does sound travel fastest though?
-Solids
Why can't sound travel in space?
-Space has no medium for the wave to travel on.
