Two parallel slits used for Young's interference experiment are .5 mm apart.The screen on which fringes are projected is 1.5 m from the slits . How far is the third dark fringe from the central bright one? Wavelength of light used is `6,000 overset@A`.

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.

In Young's double slit experiment,light of wavelength 5,000 overset @A is used.The screen on which fringes are projected is 1.5 m from the centre of the narrow slits. The third bright band on the screen is formed at a distance of 1 cm from the central bright band calculate the separation between the slits.

In a Young's experiment,two coherent sources are placed 0.9 mm apart and the fringes are observed 1 m away.If it produces the second dark fringe at a distance of 1 mm from the central fringe,the wavelength of monochromatic ligth used would be

A beam of light consisting of two wavelegnths, 6,500 overset @A and 5,200 overset @A is used to obtain interfrerence fringes in a Young's double slit experirmejnt.The distance between the slits and the screen is 120 cm. Find the distance of third bright fringe on the screen from the central maximum for the wavelength 6,500 overset @A .

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 .

In Young's double - slit exp[eriment ,two slits are 0.15 mm apart and illuminated by ligth of wavelenth 450 nm.The screen is 1 m away from the slits. Find the distance of the second bright fringe
