Chapter 12 Review - Waves

Mechanical waves are created when a source of energy causes a medium to...

• move.

• compress.

• expand.

• vibrate.

Waves that move the particles of the medium parallel to the direction in which the waves are traveling are called...

• longitudinal waves.

• transverse waves.

• surface waves.

• combination waves.

The distance between two corresponding parts of a wave is the wave's...

• amplitude.

• wavelength.

• frequency.

• speed.

The speed of a wave is its wavelength multiplied by its...

• amplitude.

• vibration.

• frequency.

• reflection.

The maximum distance that the particles of a medium move from the rest position is the...

• amplitude of the wave.

• wavelength of the wave.

• frequency of the wave.

• speed of the wave.

The interaction between two waves that meet is called...

• reflection.

• refraction.

• diffraction.

• interference.

What occurs when vibrations traveling through an object match the object's natural frequence?

• reflection

• refraction

• diffraction

• resonance

Waves combine to produce a smaller or zero-amplitude wave in a process called...

• destructive interference.

• constructive interference.

• reflection.

• refraction.

Mechanical waves are classified according to...

• their size.

• their shape.

• how they move.

• their source.

Why do you see lightning from a distant storm before you hear thunder?

• The thunder is produced after the lightning.

• Your eyes react faster than your ears.

• Light travels faster than sound.

• Sound travels faster than light.
