Waves
This type of wave vibrates matter back and forth in the medium, in the same direction the wave is moving.
What is a longitudinal wave?
The frequency of a sound wave affects what property of the sound?
What is pitch?
Sound waves cannot carry energy through this...
What is space/a vacuum?
What type of wave is a sound wave?
What is a longitudinal wave?
What is the high point of a transverse wave?
What is the crest?
This type of wave vibrates matter in a right angle to the wave direction.
What is a transverse wave?
What part of a wave measures/determines loudness?
What is amplitude?
What is a medium? Give an example.
What is the material that mechanical waves travel through.
Ex: Solid, liquid or gas
If you were in outer space, would anybody be able to hear you scream?
What is no? Sound requires a medium to travel through.
The low point of a transverse wave is called...
This type of wave does not need a medium.
What is an electromagnetic wave?
How can you tell if a wave has a high amount of energy?
What is look at the frequency? Closer together = more energy
The matter that mechanical waves travel through is known as ...
What is a medium?
Sound waves travel the fastest in what medium? The slowest in what medium?
Slowest- gases
What is the distance between the identical point in two waves?
What is wavelength?
High frequency waves have ___________ wavelengths.
What is SHORT wavelengths?
The number of wavelengths that pass a given point per second is called...
What is frequency?
What is a solid?
Explain why sound waves travel the fastest in solids?
What is particles are more tightly packed, so sound waves can vibrate from particle to particle very quickly?
How far a wave moves from its resting point is called...
What is amplitude?
Sound waves are similar to earthquake (seismic) waves because they all...
What is transmit or carry energy?
What unit is the loudness of a sound?
What is hertz?
What type of wave can travel through a vacuum?
What is an electromagnetic wave?
Explain how you would perceive the sound o fa firetruck sired as it speeds towards you AND speeds away from you.
Towards you- short wavelength/ high frequency/ high pitch
Away from you- long wavelength/ low frequency/ low pitch
The energy of a wave is directly related to which 2 wave properties?
What is amplitude and frequency?
