What is vibrates?
Sound travels in this type of wave.
What are compression waves?
Sound travels fastest through this type of medium.
What are solids?
Objects vibrating rapidly have a higher what?
What is pitch?
Some animals can make and hear ranges of sound vibrations different from these
What are humans?
Sound is a form of this kind of energy.
What is mechanical energy?
Waves transmit this from one place to another.
What is energy?
Sound travels slowest through this type of medium.
What are gases?
Objects vibrating slowly have a lower what?
What is pitch?
Bats use this to navigate and find food.
What is echolocation?
The movement of particles that creates sound waves.
What is vibration?
In sound waves, energy is transferred through the vibration of these.
What are particles?
The reason sound travels faster in solids than gases.
What is the molecules are closer together?
The number of vibrations per second is called what?
What is frequency?
Dogs can hear sounds that are this compared to human hearing.
What is higher frequency?
Sound is the transfer of this.
What is energy?
Sound cannot travel through this.
What is a vacuum (or empty space)?
Sound travels through these three mediums.
What are solids, liquids, and gases?
Larger, longer, or thicker vibrating objects create this kind of pitch.
What is lower pitch?
Animals hearing ranges of sound vibrations can be different in this.
What is frequency?
Matter that sound travels through.
What is a medium?
Sound waves cause these when they travel through matter.
What are vibrations?
The medium that molecules are the farthest apart in.
What is gas?
Smaller, shorter, or thinner vibrating objects create this kind of pitch.
What is higher pitch?
The reason why some animals can hear sounds that humans can't.
What is they have different hearing ranges?
