In Young's double slit experiement when wavelength used is `6000Å` and the screen is `40cm` from the slits, the fringes are `0.012cm` wide. What is the distance between the slits?

In the Young's double slit experiment, the slits are 0.4 cm apart and the screen is 100 cm awayIf the wavelength of light used is 5000 Å then the distance between the fourth dark fringe and central bright will be ......

In a Young's double slit experiment, the two slits are separated by 0.5 cm and the screen is at 0.5 m from the slits. If 20000 bright fringes are counted per meter on the screen, then the wavelength of light used is

In Young's double slit experiment the slits are separated by 0.24 mm. The screen is 2 m away from the slits . The fringe width is 0.3 cm. Calculate the wavelength of the light used in the experiment.

In Young's double-slit experiment the angular width of a fringe formed on a distant screen is 1^(@) . The wavelength of light used is 6000 Å . What is the spacing between the slits?

In Young's double-slit experiment the angular width of a fringe formed on a distant screen is 1^(@) . The wavelength of light used is 6000 Å . What is the spacing between the slits?

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 using lambda=6000 Å , distance between the screen and the source is 1m. If the fringe-width on the screen is 0.06 cm, the distance between the two coherent sources is

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 sepcaration between the slits is halved and the distance between the slits and the screen is doubled. The fringe width is
