When two waves combine to form a new wave with a smaller amplitude, it is called 

• Refraction
• Constructive Interference
• Resonance
• Destructive Interference

The lowest point on a wave is the:

• Amplitude
• Crest
• Trough
• Wavelength

Standing waves are created by

• Two identical waves reflecting off each other

• Two identical waves being diffracted together

• Two identical waves move through each other in opposite directions

• Two identical waves are diffracted from two identical sources
