In a Young's double slit experiment ,the fringes are formed at a distance of 1 m from double silt of separation 0.12 mm.Calculate the distance of 3rd dark b and from the centre of the screen. consider wavelength equal to 6000 `A^@`

In a Young's double slit experiment,interfernce fringes were produced on a screen placed at 1.5 m from the two slits 0.3 mm apar and illuminated by ligth of 6,400 overset@A .Find the fringe width.

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.

A beam of ligth consisting of two wavelength 4,800 overset@A and 6,000 overset@A is used to obtain interfernce fringes in a double slit experiment.The distnce between the slits is 1.8 mm and the distance of screen from the plane of slits is 1.2 m What is the lest distance from the centre of the screen,where the brigth fringes due to both the wvelength coincide?

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

A beam of ligth consisting of two wavelength 4,800 overset@A and 6,000 overset@A is used to obtain interfernce fringes in a double slit experiment.The distnce between the slits is 1.8 mm and the distance of screen from the plane of slits is 1.2 m Find the distance of the third bright frings on the screen from the central maximum for the wavelength 6,000 overset @A .
