INTERFERENCE

What is interference?
Interference is the combination of 2 or more waves that result in a single wave

Constructive Interference
When crests and troughs overlap and they create a single wave with a higher crest and deeper trough

Destructive Interference
When crests and troughs overlap they form a wave that has a smaller amplitude than the original waves. When they have the same amplitude and meet each other the result is no wave

Standing Wave
A pattern of vibration that simulates a wave that is standing still

QUIZ TIME

THE RESULT OF A CONSTRUCTIVE WAVE IS?

• Low crest
• High crest
• High trough

A STILL WAVE IS THE RESULT OF WHAT?

• When crests and troughs overlap
• When 2 deconstructive waves combine with the same amplitude
• When 2 constructive waves combine with the same amplitude
