What is a medium?

Back

A medium is the material through which a wave transfers energy, which can be solid, liquid, gas, or a combination of these.

Front

Which wave can be transmitted through empty space?

Back

Electromagnetic waves can be transmitted through empty space.

Front

What type of wave is a transverse wave?

Back

A transverse wave is a type of wave where the particle displacement is perpendicular to the direction of wave propagation.

Front

What is the medium for waves created by a rock splashing in a lake?

Back

The medium for the waves in this scenario is the water.

Front

What type of waves are sound waves?

Back

Sound waves are longitudinal waves.

Front

Define longitudinal waves.

Back

Longitudinal waves are waves in which the particle displacement is parallel to the direction of wave propagation.

Front

What is an example of a mechanical wave?

Back

An example of a mechanical wave is a sound wave, which requires a medium to travel.

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves can travel through a vacuum.

Front

What is a compressional wave?

Back

A compressional wave is a type of longitudinal wave where particles are compressed and then rarefied.

Front

What is wave frequency?

Back

Wave frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).
