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 slits are separated by 0.28mm and the screen is placed at a distance of 1.4m away from the slits. The distance between the central bright fringe and the fifth dark fringe is measured to be 1.35cm . Calculate the wavelength of the light used. Also find the fridge width if the screen is moved towards the slits by 0.4m , for the same experimental set up.

In a Young.s slit experiment, the slits are separated by 0.24 mm and the screen is kept 160 cm from the slits. If the fringe width is measured to be 0.4 cm, calculate the wavelength of light used experiment. What would be the new value of the .fringe width., if for the same set up or the same wavelength light, the screen is moved, .inwards., i.e., towards the slits by 40 cm?

In Young’s double slit experiment, the central bright fringe can be identified

In Young’s double slit experiment, the distance of screen is increased 4 times and distance between two coherent sources is reduced to half. The fringe width will

In young's double slit experiment distance between the slits is 0.5 mm. When the screen is kept at a distance of 100 cm from the slits, the distance of ninth bright fring from the centre of the fringe system is 8.835 mm. Find the wavelength of light used.

In the Youngs double slit experiment, the separation between the slits is halved and the distance between the slits and the screen is doubled, the fringe width will be :
