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

• move
• compress
• expand
• vibrate

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

• amplitude
• wavelength
• frequency
• speed

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

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

• destructive interference.
• constructive interference.
• reflection.
• refraction.

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.

A disturbance that transfers energy from place to place is called a

• wave
• medium
• vibration
• compression

The buildup of charges on an object is called

• static discharge.
• static electricity.
• positive charge.
• negative charge.

A complete, unbroken path through which electric charges can flow is a(n)

• electric circuit.
• electrical resistance.
• magnetic field line.
• magnetic pole.

Materials through which charge can flow easily are called

• insulators
• conductors
• resistors
• magnets
