Longitudinal Waves
What is another name for a longitudinal wave?
Compression Wave
What is the highest point of a transverse wave called?
Crest
What is the main difference between longitudinal and transverse waves?
Longitudinal waves move parallel to energy, while transverse waves move perpendicular
What happens when a wave bounces off a surface?
Reflection
Why does carpet and cushions help sound reduction? (term)
Absorption
In a longitudinal wave, the areas where particles are squeezed together are called what?
Compressions
What is the lowest point of a transverse wave called?
Trough
What type of wave is a sound wave?
Longitudinal
What happens when a wave bends as it moves from one medium to another?
Refraction
When a wave is taken in by a material, what is this called?
Absorbtion
What are the stretched-out areas in a longitudinal wave called?
Rarefactions
How is wavelength measured in a transverse wave?
From one crest to the next crest, or one trough to the next trough
What type of wave is a light wave?
Transverse
What happens when a wave bends around a barrier?
Diffraction
When a wave bounces off a material, what is this called?
Reflection
How is wavelength measured in a longitudinal wave?
From one compression to another compression, or from one rarefaction to another rarefaction
Define amplitude in a transverse wave.
The distance from the rest position to the crest or trough, representing energy
In which type of wave do particles move back and forth along the direction of energy transfer?
Longitudinal
Give a real-life example of reflection
Echo, mirror, light bouncing off water
Why does a pencil appear bent when placed in a glass of water?
Refraction
How does increasing the frequency of a longitudinal wave affect its wavelength?
As the wavelength increases, the frequency decreases, or as the wavelength decreases the frequency increases
How does increasing the amplitude of a transverse wave affect the energy of the wave?
higher amplitude means higher energy
Which type of wave can travel through space (a vacuum), and which cannot?
Transverse waves (like light) can travel through space; longitudinal waves (like sound) require a medium
Why do ocean waves bend around a small island instead of stopping?
Diffraction
Name a material that absorbs sound waves well.
Examples: Foam, carpet, curtains
