Amplitude
300
The distance from the starting point to a peak or valley is the ______________
Amplitude
300
What part of the ear vibrates?

300
Give an example of a medium that sound can travel through besides air (oxygen).
Ex. Water
300
What type of matter is the best way for sound waves to travel?
A solid is the best median for sound waves to travel.
400
Draw a sound wave that has low pitch and high amplitude.
The waves should be very spread out and tall.
400
The __________is the highness or lowness of a sound depending on the frequency of vibrations of the sound source.
Pitch
400
How is hearing loss caused?
When one of the structures in the ears is damaged.
400
What moves through a medium and transfers energy?
Particles
400
DOUBLE JEOPARDY!!! True or False. If there was a loud explosion in space we would not hear it.
True. There is no matter in space, so the sound waves would not have anything to bounce off of.
500
Draw a wave with high pitch and low amplitude.
There should be a lot of waves close together and short.
500
________ is any material substance which can transfer waves or energy. A substance made of matter that sounds can travel through.
Medium
500
If this structure of the ear is damaged you may have irreversible hearing loss.
Stereocilia (the hair cells in our ears)
500
How does force affect the sound source?
The bigger the force the larger the amplitude of vibrations and the louder it will be.
500
When particles bump into each other they transfer ________.
Energy
