Front

What is sound?

Back

Sound is a type of energy made by vibrations. It travels through air, water, and solid materials.

Front

How does sound travel through different materials?

Back

Sound travels fastest through solids because their particles are close together, allowing vibrations to pass quickly.

Front

What is vibration?

Back

Vibration is a rapid back-and-forth movement of particles in a medium that creates sound.

Front

Which material does sound travel through the fastest?

Back

Sound travels fastest through steel compared to air and water.

Front

What is the relationship between particle closeness and sound speed?

Back

The closer the particles are in a material, the faster sound can travel through it.

Front

What instrument produces sound with the slowest vibration?

Back

Instruments like a tuba or bass guitar produce sound with slower vibrations compared to higher-pitched instruments.

Front

What is a medium in the context of sound?

Back

A medium is a substance (solid, liquid, or gas) through which sound waves travel.

Front

How does temperature affect the speed of sound?

Back

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

Front

What is an echo?

Back

An echo is a reflection of sound that arrives at the listener after a delay.

Front

What is pitch?

Back

Pitch is how high or low a sound is, determined by the frequency of the sound waves.
