A region of high density in a wave?
waves
Explain the relationship between local particles vibrations and overall wave motion?
Most waves are caused by a vibrating object. Electromagnetic waves may be caused by charged particles.
What part of compressional waves has the area of greatest density?
compression
Areall sound waves reflected explain?
When the sound waves are reflected, the result in the producing of an echo.
Explain how ultrasonic waves can be produced in the laboratory?
using ultrasonic interferometer
How do sounds travel explain?
in waves, thus sound waves :)
A region of high density in a wave?
waves
Explain the relationship between local particles vibrations and overall wave motion?
Most waves are caused by a vibrating object. Electromagnetic waves may be caused by charged particles.
Seismic waves travel through Earth's layers at different speeds depending on the what?
Density and the composition of the different layers affect the behavior of seismic waves.
What are the waves that are produced by stars and galaxies?
Density waves (they cause the spiral arms in disc galaxies).
What does contrast electromagnetic waves with water and sound waves mean?
It means explain how electromagnetic waves are different than water and sound waves.
The speed at which seismic waves travel through Earth's layers depends upon the of those layers. temperature density shape area?
The speed of the waves depends on the density of the material.
What part of compressional waves has the area of greatest density?
compression
Areall sound waves reflected explain?
When the sound waves are reflected, the result in the producing of an echo.
Can sound waves be reflected explain why they can or cant?
9000
What are mathematical formulas to explain how mass volume and density are related?
Density = mass/volume Mass = (density) x (volume) Volume = mass/density
What slows down sound waves?
according to the equation v=1/2{gamma *pressure /density} sound waves are slowed down by=decreasing pressure and increasing volume,temparature,density of the medium
