A parallel beam of ligth of wavelength 600 nm is incident normally on a slit of width d .If the distance between teh slit and the screen is 0.8 m and the distance fo teh second order maximum from teh centre of the screen is 15 mm,calculate the width of the slit.

The light of wavelength 600 nm is incident normally on a slit of width 3 mm. Calculate the linear width of central maximum on a screen kept 3 m away from the slit.

In a Young's double slit experiment ,the distance between the slits and the screen is 1 m.If the distance between the slits is 5 mm,the fringe width is found to be 0.1 mm.Calculate the wavelength of the light used.

9 A parallel beam of light of wavelength 500 nm falls on a narrow slit and the resulting diffraction pattern is observed on a screen 1 m away. It is observed that the first minimum is at a distance of 2.5 mm from the centre of the screen. Find the width of the slit.

The light of wavelength 6,000 overset @A falls normally on a slit odf width 2 mm.Calculate the linear width of central mximum on a screen kept 4 m away from teh slit.

Light of wavelngth 600 nm is incident on a single slit of width 0.5 mm at normal incidence.Calculate the separation between two dark bbands on either side off the central maximum,if the diffration pattern is observed on a screen placed at 2 m from the slit.

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 .
