Waves

The BEST definition of a wave is…

• Any disturbance that transmits energy through matter or empty space.

• The movement of matter.

• The transmission of energy through a vacuum space.

• Matter moving through energy.

A mechanical wave travels through...

• Matter

• Vacuum

• Gas only

• Energy

An electromagnetic wave travels through...

• Matter

• Vacuum

• Solid only

• Energy

In a longitudinal wave...

• The particles of the medium move in a direction parallel to the direction in which the wave moves.

• The particles of the medium move in a direction perpendicular to the direction which the wave moves.

• The particles of the medium move in a direction opposite to the direction which the wave moves.

• The particles of the medium move in a direction 180 degrees in relation to the direction which the wave moves.

In a transverse wave...

• The particles of the medium move in a direction parallel to the direction in which the wave moves.

• The particles of the medium move in a direction perpendicular to the direction which the wave moves.

• The particles of the medium move in a direction opposite to the direction which the wave moves.

• The particles of the medium move in a direction 180 degrees in relation to the direction which the wave moves.
