Julia Science 3rd quarter Flashcards
What are Longitudinal/Mechanical Waves
Sound waves
What are Transverse/Electromagnetic Waves
Light Waves
____ waves transfer energy by the vibrations of particles in a medium
Longitudinal waves transfer energy by the vibrations of particles in a medium
A ________ is a substance that waves can travel through; it can be solid, liquid or gas.
A Medium is a substance that waves can travel through; it can be solid, liquid or gas.
_____ waves vibrate the medium back and forth along the path of the wave.
Longitudinal waves vibrate the medium back and forth along the path of the wave.
In ______ wave the particles of the medium move ____ to the direction the wave moves.
In Longitudinal wave, the particles of the medium move parallel to the direction the wave moves.
Compressions
The part of a longitudinal wave with the greatest energy
Rarefactions
The part of a longitudinal wave with the least energy
Wavelength Longitudinal
The distance between two compressions or the distance between two rarefactions
Draw a longitudinal wave
Longitudinal waves travel fastest through _________.
Longitudinal waves travel fastest through Solids
Longitudinal waves travel 2nd best through
Longitudinal waves travel 2nd best through liquids.
Longitudinal waves 3rd best through _________.
Longitudinal waves 3rd best through Gases
Longitudinal waves CANNOT travel through ______.
Longitudinal waves CANNOT travel through Vacuum (empty space)
_____ waves transfer energy without traveling through a medium.
Transverse waves transfer energy without traveling through a medium.
Even though _____ waves don’t NEED a medium, they can still travel through gases, liquids, and some solids.
Even though transverse waves don’t NEED a medium, they can still travel through gases, liquids, and some solids.
_______ waves vibrate with an up an down motion. the particles in the medium move _____ to the direction the wave is traveling.
Transverse waves vibrate with an up an down motion. the particles inthe medium move perpendicular to the direction the wave is traveling.
Line of origin
the “resting potion” of the wave when it is not moving
Crest
part of the transverse wave with the greatest energy (highest point)
Trough
Part of a transverse wave with the least energy (lowest point)
Wavelength Transverse
The distance between two Crests or the distance between two trough
Amplitude
The height of the waves from the line of origin
Draw a Transverse wave
Transverse waves travel through _____ best
Vacuum
Transverse waves travel through ______ 2nd best.
Gases
Transverse waves travel through _______ 3rd best
liquids
Transverse waves travel slowest through _______.
Solids
The Wave carries ______ with it
The Wave carries Energy with it
