They discovered that light could be made to interfere, which results from the superposition of waves 2- Define the incoherent light? It is light whose waves are not in phase 3- Define the coherent light? It is Light made up of waves of the same wavelength that are in phase with each other 4- How we can create a coherent light?  It can be created by a single point source.  It can be created by multiple point sources when all point sources are in phase. This type of coherent light is produced by a laser. 2 Chapter 8 – Interference and Diffraction Interference of Coherent Light 1- What is the prerequisite for a clear interference of light waves? The light waves should be from coherent sources. 2- What was Thomas Young experiment? In his experiment, monochromatic light from a small source (single point source). was passed through two closely spaced slits and produced an interference pattern. 3- Define interference fringes The pattern of bright and dark band  Note1: There are two types of waves interference (constructive – destructive) Constructive Destructive When two waves meet in such a When two waves meet in such a way way that their crests line up that the crest of one wave meets the together. trough of another.  Note2: In the interference pattern:  The Bright band represents an area where a constructive interference occurs.  The dark area represents an area where a destructive interference occurs. 3 Chapter 8 – Interference and Diffraction Exercises:  Rely on the following figure to fill in the table.
