The minimum value of d os that there is a dark fringe at O is `d_(min)`. For the value of `d_(min)`, the distance at which the next bright fringe is formed is x. Then

Consider the arrangement shown in figure-6.38. The distance D is large compared to the separation d between the slits. (a) Find the minimum value of d so that there is a dark fringe at O. (b) Suppose d has this value. Find the distance x at which the next bright fringe is formed. (c ) Find the fringe width.

In the arrangment shown in fin. Find the distance x at which the next fringe is formed.

In the arrangment shown in fin. Find the distance x at which the next fringe is formed.

Calculate the fringe width if the distance between 7th dark fringe and 17th bright fringe is 19 mm.

In Young's double slit experiment, the distance between two coherent sources is 1 mm and the distance between the slits and the screen is 1 m. If the 10th dark fringe is at a distance of 4.75 mm from the central bright fringe, calculate the distance of 5th bright fringe from the central bright fringe.

The distance of nth bright fringe to the nth dark fringe in Young's experiment is equal to
