Interference

Interference

Interference

When two or more waves meet at the same point in space and at the same time

Superposition

Superposition

When waves overlap in space and time the displacements add at every point

Constructive Interference

Two or more waves which overlap and produce a resulting wave of increased amplitude -a wave that is the result of two or more waves added together

Destructive Interference

Two or more waves where the crest parts of one wave overlap trough parts of another, resulting in a wave of decreased amplitude -a wave that is the result of two or more waves substracted from one another
