Mechanical vs. Electromagnetic Waves Review

Front

What is the wavelength of a wave?

Back

The wavelength is the distance between two consecutive points that are in phase on a wave, such as from one crest to the next crest.

Front

How does a compressional wave travel?

Back

A compressional wave travels in a parallel direction to the motion of the particles in the medium.

Front

What is the highest point on a transverse wave called?

Back

The highest point on a transverse wave is called the crest.

Front

What type of wave is a light wave?

Back

A light wave is an example of an electromagnetic wave.

Front

What is rarefaction in a wave?

Back

Rarefaction is the part of a compressional wave where the particles are spread apart.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that the particles of a wave move from their rest position.

Front

What is frequency in terms of waves?

Back

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

Front

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves do not and can travel through a vacuum.

Front

What is a trough in a wave?

Back

A trough is the lowest point on a transverse wave.

Front

What is the rest position of a wave?

Back

The rest position is the position of the medium when there is no wave passing through it.
