The interference differs from diffraction in that

The main difference in the phenomenon of interference and diffraction is that

Both in interference and diffraction phenomena, alternate dark and bright fringes are obtained on screen i) generally fringe width is same in interference and not same in diffraction ii) the central fringe in interference has maximum brightness and thei intensity gradually decreases on either side iii) in interference the intensity of all bright fringes in same iv) both the phenomena are produced from same coherent sources

Write the difference between the interference pattern and diffraction pattern.

A : There is no specific important physical difference between interference and diffraction. R : When there are only few sources (say two), the result is usually called interference, but if there is a large number of sources, the result is diffraction.

Is Young's experiment an interference or a diffraction experiment, or both?

Mention three differences between interference and diffraction. Why is the size of the objective of astronomical telescope generally large?
