Interference

|
A single point creates waves with concentric circles of light and dark bands. |
This picture does not show an interference pattern. It is simply the concentric waves of two points sources drawn in the same plane. Contrast this with the image to the right |
This is the interference pattern of two waves. The two waves add or subtract to form the light and dark regions of the interference pattern |
 |
Waves are not simple two dimensional objects. When they interfere with each other, peaks and valleys are formed. Many interference patterns look like two-dimensional systems of light and dark bands because they are being viewed from above. In this picture the system tilted so it can be viewed from the side. | |
