Interference and difiraction
The outline of this chapter is as follows In Section 9 1 we do the warm-up case of two waves interfering The setup consists of a plane wave passing through two very narrow (much narrower than the wavelength of the wave) slits in a wall and these two slits may be considered to be the two sources |

INTERFERENCE DIFFRACTION AND POLARIZATION
DIFFRACTION Diffraction is an interference effect caused by reflective strips separated by a non-reflective strip • Compact discs have information coded along narrow reflective lines • In this illustration light from neighboring lines has a path length difference equal to one red wavelength That part of the CD appears red |

define the path-length difference as the difference between the distance a point is from one source and the distance the point is from the second source For point A in Figure 25 1(b) which is on the perpendicular bisector of the line connecting the sources the path-length difference is zero because point A is equidistant from both sources |
What is the difference between diffraction and interference?
One major basis of the difference between diffraction and interference is regarding the occurrence of these two phenomena. Diffraction takes place when a wave comes across an obstacle while interference happens when waves meet each other. Diffraction refers to the spreading out of waves when their passing takes place through an aperture.
Can interference occur without diffraction?
Yes, in the case of thin-film interference, the phenomena of interference happen without diffraction. Thin-film interference is a natural phenomenon in which light waves reflected by the upper and lower boundaries of a thin film interfere with one another, either enhancing or reducing the reflected light. What is constructive phasing?
Why does interference happen during diffraction?
Why does interference happen during diffraction? Diffraction and interference are the same phenomena, and there is no clear distinction. Interference is usually used to characterize the effects of a very small number of slits or beams, while diffraction is used to characterize a large number of slits (such as a grating) or a large area such as the diffraction from from a telescope mirror.
How is diffraction of light related to interference?
Interference is a feature caused by waves from two independent coherent sources, whereas Diffraction is caused by secondary wavelets that originate from the same wave but occur in various areas of it. In interference, all maxima have the same magnitude of intensity. While, the magnitude of the maxima may vary.
