Wave Interactions

Which wave in the diagram has the greatest wavelength?

• 1
• 2
• 3
• 4

Which wave behavior do noise cancelling headphones use?

• diffraction
• refraction
• constructive interference
• destructive interference

The combination of two waves to form a larger amplitude is what type of interference?

• Constructive
• Destructive
• Diffractive
• Refractive

Waves can meet and form a smaller amplitude.  If this occurs, it is called

• Constructive
• Destructive
• Diffractive
• Refractive

• 2 waves are in phase so they show constructive interference

• 2 waves are out of phase so they so destructive interference

• 2 waves are in phase so diffraction is happening

• 2 waves are out of phase so diffraction is happening

• 2 waves are in phase so they show constructive interference

• 2 waves are out of phase so they so destructive interference

• 2 waves are in phase so diffraction is happening

• 2 waves are out of phase so diffraction is happening

Waves that require a medium are called 

• mechanical waves
• transverse waves
• light waves
• gamma rays

What is transferred by a wave?

• energy

• matter

• particles

• mass

which material does sound travel the fastest?

• solid 
• liquid 
• gases

What happens to the frequency of a wave when the amplitude is tripled?

• the frequency is tripled

• the frequency is a third of what it was

• amplitude does not affect frequency
