Interference

                          Interference 

The difference between a constructive and a destructive interference is that a constructive interference is the crest of a wave that is super positioned with another crest but a difference wave it can also be a trough with a trough and all of this will allow to increase the amplitude. A destructive interference is when the crest of a wave is also super positioned with the trough of another wave but its to decrease the amplitude. An example of something that interferes and makes something smaller is when hot water is in contact with snow. The hot water makes contact with the snow making the snow dissolve into the ground. An example of something that interferes with and makes it larger is water and a plant. The plant needs water to grow which makes the plant increase in size. It becomes larger than it already is.
