6th Grade Waves Review

Front

What are Mechanical Waves?

Back

Mechanical waves are waves that require a medium (solid, liquid, or gas) to travel through. Examples include sound waves and water waves.

Front

What are Electromagnetic Waves?

Back

Electromagnetic waves are waves that do not require a medium to travel and can move through a vacuum. Examples include light waves and radio waves.

Front

What is a Rarefaction in a wave?

Back

A rarefaction is a region in a longitudinal wave where the particles are spread apart, resulting in lower pressure.

Front

What is a Crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a Trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is Constructive Interference?

Back

Constructive interference occurs when two waves meet and their crests and troughs align, resulting in a wave of greater amplitude.

Front

What is Destructive Interference?

Back

Destructive interference occurs when two waves meet and their crests and troughs do not align, resulting in a wave of lesser amplitude.

Front

What is Frequency in terms of waves?

Back

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

Front

What is the Period of a wave?

Back

The period is the time it takes for one complete wave cycle to pass a point, measured in seconds.

Front

What is a Longitudinal Wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave's travel.
