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 using light of wavelength 5000Å, the fringe width is 0.6 cm. If the distance between the slit abd screen is reduced to half , calculate the new fringe width.

In Young's double slit experiment while using a source of light of wavelength 4500 A, the fringe width is 5mm. If the distance between the screen and the plane of the slits is reduced to half, what should be the wavelength of light to get fringe width 4mm?

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 the fringe width obtained is 0.6cm , when light of wavelength 4800 Å is used. If the disatance between the screen and the slit is reduced to half, what should be the wavelength of light used to obtain fringes 0.0045 m wide ?

In a Young's double slit experiment,the fringe width obtained is 0.6 cm,when light of wavelength 4,800 overset @A is used .If the distance between the screen and the slit is reduced to half,what should be the wavelength of light used to obtain fringes 0.0045 m wide?

In Young’s double slit experiment, using light of wavelength 600 nm, 10^(th) bright fringe is obtained on a screen, 3mm from the centre of the pattern. If the screen is 120 cm away from the slits, calculate: (i) Distance between the two slits, (ii) Fringe width, i.e. fringe separation.
