Waves Review #1

Front

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.

Front

What is the highest part of a wave called?

Back

The highest part of a wave is called the Crest.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a point in a given amount of time, usually measured in Hertz (Hz). A higher frequency means more waves are passing in that time.

Front

What type of wave is characterized by particle movement parallel to the direction of wave propagation?

Back

A Longitudinal wave is characterized by particle movement that is parallel to the direction of wave propagation.

Front

What is the term for the lowest part of a wave?

Back

The lowest part of a wave is called the Trough.

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is amplitude in relation to waves?

Back

Amplitude is the maximum distance that the particles of a medium move from their resting position when a wave passes through.

Front

How does sound travel through different mediums?

Back

Sound travels fastest in solids, slower in liquids, and slowest in gases due to the density and elasticity of the medium.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, particles move perpendicular to the direction of wave propagation, while in longitudinal waves, particles move parallel to the direction of wave propagation.

Front

What is an example of a transverse wave?

Back

An example of a transverse wave is a wave on a string or electromagnetic waves like light.
