Waves Review Lesson 8 & 9

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

• Move
• Expand
• Vibrate
• Compress

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

• Surface Waves
• Combination Waves
• Longitudinal Waves
• Transverse Waves

The maximum distance that the particles of a medium move from the rest position (equilibrium) is the

• Wavelength of the Wave
• Frequency of the Wave
• Amplitude of the Wave
• Speed of the Wave

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

• Wavelength
• Frequency
• Amplitude
• Speed

The interaction between two waves that meet is called

• refraction
• reflection
• diffreaction
• interference

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

• Your eyes react faster than your ears
• Light travels faster than sound
• The thunder is produced after the lightening

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

• Destructive Interference
• Reflection
• Refraction
• Constructive Interference

Mechanical waves are classified according to

• how they move
• their source
• their shape 
• their size

As the frequency of a wave traveling at constant speed increases, its ____________________ decreases.

• wavelength
• amplitude
• speed
• reflection

           In a longitudinal wave moving along a spring, areas where the coils are farthest apart are called ____________________.

• interference
• Compression
• Rarefraction
• Diffraction
