Sound Propagation and Pitch Changes

Front

What is necessary for sound to occur?

Back

Vibrations are necessary for sound to occur.

Front

How does the amount of water affect pitch?

Back

The more water there is, the lower the pitch.

Front

How is energy transferred in sound waves?

Back

Energy is transferred through the vibration of particles in a medium.

Front

What type of energy is sound?

Back

Sound is a form of mechanical energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is sound propagation?

Back

Sound propagation is the way sound travels through different mediums.

Front

What medium can sound travel through?

Back

Sound can travel through solids, liquids, and gases.

Front

What happens to sound in a vacuum?

Back

Sound cannot travel in a vacuum because there are no particles to vibrate.

Front

What is pitch?

Back

Pitch is how high or low a sound is.

Front

How does temperature affect sound speed?

Back

Sound travels faster in warmer temperatures because particles move more quickly.
