Two wavelengths of sodium light of 590 nm nd 596 nm are used in turn to study the diffraction taking place at a single slit of aperture `2 xx 10 ^(-6)m`.Calculate the separation between the positions of first maxima of the diffraction pattern obtained in the two cases.

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 parallel monochromatic beam of light is incident normally on a narrow slit.A diffraction pattern is formed on a screen placed perpendicular to the direction of the incident beam.At the first minimum of the diffraction pattern,the phase difference between the rays coming from the two edges of the slit is

In Young's double slit experiment,usin light of wavelength 400 nm,interference fringes of width X are obtained .The wavelength of light is increassed to 600 nm and the separation between the slits is halved.If one wants the observed fringe width on the screen to be the same in the two caes,find the rati of the distance between the screen and the plane of the interfering sources in the two arrangements.

in a Youing's double slit experiment,bicromatic light of wavelengths 400 nm and 560 nm are used.The distance between the slits is 0.1 mm and the distance between the plane of the slits and screen is 1.0m. the minimum distance between two successive regions of complete darkness is

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?

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.

Two spheres of 1kg mass each are separated by 3 m. Calculate the gravitational force between then. Given G = 6.67 xx 10^ -11Nm^2//kg^2 .

Red light of wavelenggth 6,500 overset @A from a distant source falls on a slit 0.5 mm wide.What is the distnce between two dark bands on each side of central brigth band of diffraction pattern observed on a screen placed 1.8 m from the slit?

In Young's double slit experiment,two slits are separated by 3 mm distance and illuminated by ligth of wavelength 480 nm.The screen is at 2 m from the plane of the slits.Calculate the separtion between the 8th bright finge and the 3rd dark fringe obsrved with respect to the central brigth fringe.

For a given single slit,the diffraction pattern is obtained on a fixed screen,first by using red ligth and then with blue light.In which case,will the central maxima,in the observed diffraction pattern,have a larger angular width?
