Two waves with the same amplitude, frequency, and wavelength can interfere with each other destructively if they have a different _______.

• crest

• beat

• node

• phase

The addition of multiple reflections of a sound to the original sound.

• resonance

• reverberation

• constructive interference

• diffraction

When two frequencies of sound are close, but not identical, the sound waves drift in and out of phase and create _________.

• superposition

• interference

• resonance

• beats

The superposition of waves means

• The bending of waves as they enter a new medium

• Waves add together.

• The bending of waves as they pass through openings or around corners

• the alignment of electromagnetic waves in one direction

• echo

• superposition

• beat

• amplitude
