(Savvas 17.1) Ch 17.1 Mechanical Waves

Waves significantly transfer

• matter.

• energy.

• both matter and energy.

• neither matter or energy.

What can mechanical waves travel through? (Mark all that apply.)

• Solids

• Liquids

• Gases

• Vacuum

  (empty space)

The material through which a wave travels is called a(n) _________________

• medium

• conductor

• insulator

• vacuum

A mechanical wave is created by

• a disturbance in a medium.

• a change in temperature.

• a chemical reaction.

• an electrical signal.

What are the types of mechanical waves? (Mark all that apply.)

• transverse waves

• longitudinal waves

• surface waves

• light waves

The highest point of a transverse wave above the rest position is the _______________ and the lowest point below the rest position is the _______________.

• crest; trough

• trough; crest

• peak; valley

• apex; base

A wave in which the vibration of the medium is parallel, or in the same direction as, the direction in which the wave travels is called a(n) _______________.

• longitudinal wave

• transverse wave

• surface wave

• standing wave

A wave in which the vibration of the medium is perpendicular, or at right angles, to the direction in which the wave travels is called a(n) _______________.

• longitudinal wave

• transverse wave

• surface wave

• standing wave

When a longitudinal wave carries energy through a spring, the area where the coils of a spring are closer together than they would be in the rest location is called a(n) _______________.

• compression

• rarefaction

• oscillation

• amplitude

When a longitudinal wave carries energy through a spring, the area where the coils of a spring are farther apart than they would be in the rest location is called a(n)

• compression.

• rarefaction.

• oscillation.

• amplitude.
