The Nature of Waves

All waves

• are physical environments in which waves can occur.

• move perpendicular to the direction of the wave.

• move parallel to the direction of the wave.

• are disturbances made by energy within a medium or space.

• trough.

• compression.

• rarefaction.

Mechanical waves need a _______, where an electromagnetic wave do not.

• crest

• medium

• compression

• surface

In what way does a transverse way move?

• parallel to the direction of the wave

• tangentially to the direction of the wave

• at an 180 degree angle

• perpendicular to the direction of the wave

In what way does a longitudinal wave move?

• parallel to the direction of the wave

• back and forth

• tangentially to the direction of the wave

• perpendicular to the direction of the wave

What type of wave is this?

• compressional

• transverse
