When two
waves are totally identical, we say that the waves are in a phase.
Constructive Interference:
When we join the two identical waves then the resultant
wave will be a wave having double the amplitude of each wave. This process is
known as Constructive Interference.
Phase Cancellation:
But if two wave are totally identical (phase) but are inverse
and they are added then the amplitude of the resultant wave will be cancelled out,
then the there will be neither peak nor a trough and there will only be a
straight line. This process is known as destructive Interference (Phase
Cancellation).
Good Examples: Karaoke Devices, Noise reduction Headphones
etc.
