In the arrangment shown in fin. Find the fringe width.

Answer the following: With a diagram showing the Young's arrangement for producing 'a sustained interference pattern, obtain the expression for the width of the interference fringes obtained in this pattern.

Fringe width decrease with increase in

Statement I: Fringe width depends upon refractive index of the medium. Statement II: Refractive index changes optical path of ray of light forming fringe pattern.

State the importance of coherent sources in the phenomenon of interference. In Young's double slit expet-ment to produce interference pattern obtain the conditions for constructive and destructive interference. Hence deduce the expression for the fringe width. How does the firinge width get affected, if the entire experimental apparatus of Young's is immersed in water ?

Assertion : When a thin transparent sheet is placed in front of both the slits of Young's experiment, the fringe width will remains same. Reason : In Young's experiment, the fringe width is directly proportional to wavelength of the source used.

A fringe width of a certain interference pattern is beta=0.002 cm What is the distance of 5th dark fringe centre?

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 the intensity gradually decreases on either side III) in interference the intensity of all bright fringes is same IV) both the phenomena are produced from same coherent sources.

Statement I: In Young's experiment, the fringe width for dark fringes is different from that of white fringes. Statement II: In Young's doulbe-slit experiment, when the fringes are observed with a source of white light then only black and bright fringes are observed.

A narrow beam of 100eV electrons is fired at two parallel slits very close to each other. The distance between the slits is 10Å. The electrons waves after passing through the slits interfere on a screen 3m away from slits and form interference fringes. Find the width of the fringe.
