Light of wavelength 6000 `overset(@)A` is used to obtain interference fringe of width 6 mm in a young's double slit experiment. Calculate the wavelength of light required to obtain fringe of width 4 mm if the distance between the screen and slits is reduced to half of its initial value.

When two narrow slits separated by a small distance are illuminated by a light of wavelength 5 xx 10^(-7) m , interference fringes of width 0.5 mm are obtained on a screen . What should be the wavelength of light source to obtain fringes 0.3 mm wide , if the distance between the screen and the slits is reduced to half of the initial value .

In Young's double slit experiment, the slits are 3 mm apart. The wavelength of light used is 5000 Å and the distance between the slits and the screen is 90 cm. The fringe width in mm is

In Young's double slit experiment if wavelength of light is doubled without changing other conditions, the fringe width will

In Young's double slit experiment, while using a source of light of wavelength 4500 Å , the fringe width obtained is 0.4 cm. If the distance between the slits and the screen is reduced to half , calculate the new fringe width.

In Young’s double slit experiment, the wavelength of the light used is doubled and distance between two slits is half of initial distance, the resultant fringe width becomes

In a Young's double-slit experiment the fringe width is 0.2mm . If the wavelength of light used is increased by 10% and the separation between the slits if also increased by 10%, the fringe width will be

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
