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 light of wavelength 600 nm from a distant source falls on a single slit 1.00 mm wide and the resulting diffraction pattern is observed on a screen 2m away. What is the distance between the first dark fringes on either side of the central fringe?

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.

The Young's double-slit experiment is done in a medium of refractive index 4//3. A light of 600 nm wavelength is falling on the slits having 0.45 mm separation. The lower shift S_(2) is covered by a thin glass sheet of refractive index. 1.5. The interference pattern is observed on a screen placed 1.5 m from the slits as shown in Figure a. Find the location of central maximum (bright fringe with zero path difference) on the y-axis.

Light of wavelength 550nm is incident as parallel bea on a silt of width 0.1 mm.Find the linear width and the angular width of the principal maxima in the resulting diffraction pattern on a screen kept at a distance of 1.1 m from the slit.Which of these widths would not change,if the screen were moved to a distance of 2.2 m from the slit?

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 Young's double-slit experiment is done in a medium of refractive index 4//3. A light of 600 nm wavelength is falling on the slits having 0.45 mm separation.
