StellarDouble-Slit
Another example of diffraction is called the Double-Slit which consists of two slits that are close together which create uniform fringes of light on the other side of the two slits. These slits are thin enough that single slit diffraction does not occur. Originally discovered by Thomas Young, the double slit showed the wave nature of light. In this kind of diffraction, two circular waves are created at each slit. The interference between these two circular waves creates the uniform bright and dark fringes.
