2. What is interference?
Interference is the addition of two or more waves that result in a wave pattern.
Interference usually refers to interaction of waves that are correlated or coherent with each other.
They come from the same source or have the same (or almost the same) frequency.
Interference of waves coming from two point sources.

3. Superposition Principle
Super positioning happens most commonly in waves with different frequencies.
Instead, waves of different frequency and wave lengths are often found overlapping in the same region of space at the same time.
The principle states that the net response at a given place in time caused by two or more vibrations is the sum of the regular responses which would have been caused by each of the vibrations individually.

4. Phase shift The phase in a wave is the fraction of a completed cycle.
A phase shift is the movement of that completed cycle (left or right) along the x-axis.

5. Nodes, Antinodes and Loops
A node is a point along a standing wave where the wave has minimal amplitude.
An antinode is the opposite of the node (the point of the standing point is a maximum). This occurs midway between the nodes.
