For observable diffraction, the wavelength must be greater than or equal to the width of the aperture. For observable diffraction, the wavelength must be greater than or equal to the width of the aperture.
### Interference ### Two-point interference
When two points create waves, their wavefronts spread out in all directions. If waves are emanated from two points at the same speed and frequency, they form **nodal** and **anti-nodal** lines.
