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

• expand

• compress

• vibrate

• move

Waves that move the particles of the medium parallel to the direction in which the waves are traveling are called (select 2)

• seismic waves

• surface waves

• transverse waves

• longitudinal waves

• compressional waves

The speed of a wave is its wavelength multiplied by its

(a)   .

• reflection

• vibration

• amplitude

• frequency

• refraction

The interaction between two waves that meet is called

• refraction

• diffraction

• reflection

• interference

Waves combine to make a wave with larger amplitude in a process called
