Flashcard on Sound

Front

What is sound?

Back

Sound is a type of energy that is produced by vibrations and travels through a medium such as air, water, or solids.

Front

How is sound produced?

Back

Sound is produced from vibrations that disturb the surrounding molecules.

Front

Can sound travel in outer space?

Back

No, sound cannot travel in outer space because it requires a medium (solid, liquid, or gas) to travel through.

Front

What is a medium in the context of sound?

Back

A medium is a substance through which sound waves can travel, such as air, water, or solids.

Front

How does sound travel through different mediums?

Back

Sound can be transmitted through solids, liquids, and gases in waves.

Front

Why does sound travel faster in solids than in gases?

Back

Sound travels faster in solids because the particles in solids are closer together, allowing vibrations to pass through more quickly.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves (which require a medium) and electromagnetic waves (which do not require a medium).

Front

What is frequency in sound?

Back

Frequency is the number of vibrations or cycles that occur in a sound wave per second, measured in Hertz (Hz).

Front

What is pitch?

Back

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