How does the rate (how fast or slow) of vibration affect the sound of a guitar?

• The rate of vibration allows sound to be reflected.
• The rate of vibration affects the tuning of the guitar.
• Changing the rate of vibration can vary the pitch of the sound.
• Changing the rate of vibration can vary the volume of the sound.

Which numbered part of the instrument in each picture would have the highest pitch?

Aaiden noticed that the sound of a spoon taping his glass soda bottle changed when water was added to it. What was the cause?

• The thickness of the glass interferes with the vibration of the fork.
• Sound quality varies with the type of liquid used.
• Sound travels faster in water than through the air.
• The amount of water in the glass affects how fast the glass vibrates.

How is the way a guitar makes sound different from how a drum makes sound?

• A guitar makes sound by hitting the object: a solid hits another solid; while the drum makes sound by vibrating strings
• Both a drum and a guitar make sound by causing strings to vibrate
• A drum makes sound by hitting the object (the drum cover vibrates), while the guitar makes sound by causing strings to vibrate.
• Both a drum and a guitar make sound by hitting the object: a solid object hits another solid object

Which is true?

• Sounds are fluids that travel through air.
• Sounds are waves that travel through matter.
• Sounds are gases that transform into vibrations.
• Sounds are forms of energy that are converted from light.

How does sound travel?

• Sound is a form of electromagnetic radiation that travels in straight paths called rays.
• Sound is a form of mechanical energy produced and transmitted by vibrating matter that travels in transverse waves.

• Sound is a form of mechanical energy produced and transmitted by vibrating matter that travels in compression waves.

• Sound is a form of mechanical energy produced by moving electrons that travels through conductors.

Which statement is true?

• Objects have a higher pitch because they can vibrate more quickly. These objects tend to be larger in size
• Objects have a higher pitch because they can vibrate more quickly. These objects tend to be smaller in size.
• Objects have a higher pitch because they can vibrate less quickly. These objects tend to be larger in size
• Objects have a higher pitch because they can vibrate less quickly. These objects tend to be smaller in size
