What is a medium in the context of sound waves?

Back

A medium is a substance (solid, liquid, or gas) through which sound waves travel. In outer space, there is no medium, which is why sound cannot be heard.

What are transverse waves?

Back

Transverse waves are waves where the particle movement is perpendicular to the direction of wave propagation, such as in water waves.

What are longitudinal waves?

Back

Longitudinal waves are waves where the particle movement is parallel to the direction of wave propagation, such as sound waves.

What are compressions in a longitudinal wave?

Back

Compressions are the regions in a longitudinal wave where the particles are closest together.

Front

What are rarefactions in a longitudinal wave?

Back

Rarefactions are the regions in a longitudinal wave where the particles are spread apart.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, particle movement is perpendicular to wave direction, while in longitudinal waves, particle movement is parallel to wave direction.

Front

What type of wave is a sound wave?

Back

A sound wave is a longitudinal wave.

Front

What type of wave is a light wave?

Back

What is wave amplitude?

Back

Amplitude is the maximum displacement of points on a wave from the rest position, indicating the energy of the wave.

What is wave frequency?

Back

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