The highness or lowness of a sound depends on the frequency of vibrations of the sound source, is the definition of: 

• Amplitude

• Frequency

• Pitch 

• Vibrations

 If a sound source is producing sound with a steady pitch and is vibrating with a frequency of 1 waves per 1 second, then how many times would it move back and forth in 15 seconds?

• 1

• 10

• 15

• 20

When there is a greater the force acting on a sound maker there is  ___________

• a bigger vibration.

• a smaller vibration.

• no vibration.

• no sound.
