In young's double slit experiment, distance between the slits is `1mm. The fringe width is found to be 0.6 mm. When the screen is moved through a distance of 0.25 m, the fringe width becomes 0.75 mm. Find the wavelength of light used.

In a Young's double slit experiment distance between the slits is 1 mm. The fringe width is found to be 0.6 mm. When the screen is moved through a distance of 0.25 m away from the plane of the slit, the fringe width becomes 0.75 mm. Find the wavelength of light used.

In young's double slit experiment, if the distance between the slits is halved and the distance between the slits and the screen is doubled, the fringe width becomes

In Young's double slit experiment, the distance between the two slits is 0.1 mm, the distance between the screen and the slit is 100 cm. if the width of the fringe is 5 mm, then the wavelength of monochromatic light used is

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 a Young's double slit experiment ,the distance between the slits and the screen is 1 m.If the distance between the slits is 5 mm,the fringe width is found to be 0.1 mm.Calculate the wavelength of the light used.

In Young's double slit experiment with a mono - chromatic light of wavelength 4000 A^(@) , the fringe width is found to be 0.4 mm. When the slits are now illuminated with a light of wavelength 5000A^(@) the fringe width will the
