Draw schematic diagram of Young experiment and drive `B=(lamda D)/d` for the distance between two consecutive bright interference fringes.

Write down the formula for distance between two consecutive bright fringes or two consecutive dark fringes.

In Young's experiment, the distance between two slits is 1 mm and the distance between two consecutive bright fringes is 0.03 cm. Now, on displacing the screen away from the slits by 50 cm, the distance between two consecutive dark fringes is doubled. Find the wavelength of light used.

The figure shown a schematic diagram showing the arrangement of young's double slit experiment. Q. If the distance D is varied then choose the correct statement (s)

In Young's experiment distance between two consecutive dark fringes is 2 mm, distance between central maximum and third dark fringe will be ......

The figure shown a schematic diagram showing the arrangement of young's double slit experiment. Q. If the distance d is varied, then identify the correct statement-

In a Young’s double-slit experiment, the slits are separated by 0.28 mm and the screen is placed 1.4 m away. The distance between the central bright fringe and the fourth bright fringe is measured to be 1.2 cm. Determine the wavelength of light used in the experiment.

In Young's double slit experiment, the distance between two slits is made three times then the fringe width will become ......

A point sources S emitting light of wavelength 600nm is placed at a very small height h above the flat reflecting surface AB (see figure).The intensity of the reflected light is 36% of the intensity.interference firnges are observed on a screen placed parallel to the reflecting surface a very large distance D from it. (A)What is the shape of the interference fringes on the screen? (B)Calculate the ratio of the minimum to the maximum to the maximum intensities in the interference fringes fromed near the point P (shown in the figure) (c) if the intenstities at point P corresponds to a maximum,calculate the minimum distance through which the reflecting surface AB should be shifted so that the intensity at P again becomes maximum.
