Similarities Between Diffraction and Interference
There are following similarities between Diffraction and Interference
- Both Diffraction and Interference are phenomena of waves.
- Both deal with wavefronts.
- The superposition of waves occurs in both diffraction and interference.
Difference Between Diffraction And Interference
Diffraction and Interference are two important phenomena studied in Wave Optics. These phenomena are linked to the Wave Nature of the matter. We know that when photons are emitted from the source they start oscillating in space and the locus of all such oscillating particles in the same phase is called Wavefronts. As per Huygens Wave Theory, each point on the Wavefront acts as a source of secondary Wavelets which later add up to give a new Wavefront. The sources of these Wavefronts can be coherent or non-coherent depending upon whether the phase difference is constant or not. These wavefronts interact with each other and with other particles to give rise to the phenomena of Interference and Diffraction respectively.
In this article, we will learn about what is diffraction, what is interference and what are the differences between Diffraction and Interference.
