In an experiment the two slits are `0.5mm`apart and the fringes are observed to`100cm`from the plane of theslits ,The distance of the`11th`bright fringe from the ist bright fringe is `9.72mm`.calcualte the wavelength

In young's double slit experiment,the two slits are 0.5 mm apart .The screen is placed 1 m away from the slits .The distance of 11th fringe from the first fringe is 1.0 cm.Calculate the wavelength of light used.

In a Young's double slit experiment, the slits are 0.03 cm apart and the screen is placed 1.5m away from the plane of the sources. The distance between the central bright fringe and the fourth bright fringe is measured to be 1 cm. Determine the wavelength of the light used.

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 Young's double slit experiment, the slits are 0.2 mm apart and the screen is 1.5 m away. It is observed that the distance between the central bright fringe and fourth dark fringe is 1.8 cm . Calculate wavelength of light used.

In a Young's double slit experiment the slits separated by 0.3 mm and screen is 1.5 m awavy from the plane of slits .Distance between fourth bright fringes on both sides of central bright fringe is 2.4 cm .The frequency of light used is ______ xx10^(14)Hz .

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