Constructive Wave Interference

• Constructive interference is when the two waves come together, and their crests and troughs match up.
• Constructive wave interference results in a greater amplitude of the crest and trough
• e.g. Two speakers emitting the same sound, it sounds louder than a single speaker
• e.g. A water wave is reflected off a barrier meeting up with an incoming wave making the crest higher
• The amplitudes are added together, and is increased
