In a single slit diffraction pattern, the distance between the 1st minima on the right and the 1st minima on the left is 5.2 mm. The screen on which the pattern is displayed is 80 cm from the slit. If `lambda= 5460 overset@A`. Calculate the slit width.

Light of wavelength 6000 overset (@)(A) is incident normally on a slit . The first minimum in the diffraction pattern is observed to be at a distance of 6 mm from the central maximum on a screen , which is at a distance of 2 m from the slit . Calculate the width of the slit .

In Young's experiment, the distance between two slits is 0.8mm and the distance of the screen from the slit is1.2 m. If the fringe width is 0.79 mm, the wavelength of light used is

In a biprism experiment, the distance between the slit and screen is 1 m and distance between the images of the slit is 0.274 mm. If the fringewidth is 0.2 cm, the wavelength of light is

In a biprism experiment the distance between the slit and the screen is 1 m and the separation of the two virtual images of the slit is 0.4 mm. An interference pattern is obtained with light of wavelength 5.5 xx 10^-7 m . Find the distance between the 3rd and the 8th bright band.

In Young's double slit experiment , the distance between two slits is 0.1 mm . The distance between the screen and slits is 20 cm . If the slit is illuminated by a light of wavelength 5460 overset (@)(A) then the angular position of the first dark fringe is

In a biprism experiment , the distance between the virtual images of the slits is 2.5 mm and the eyepiece is at a distance of 1 m from the slits . If the fringe width is 0.3 mm then the frequency of source of light is

In biprism experiment the distance between the two virtual images of the slit is 0.1 cm and the distance between the slit and biprism is 1 m .If the band width is 0.058 cm , calculate the wavelength of light .

In single slit diffraction a = 0.14 mm, D = 2 m and distance of second dark band from central maxima is 1.6 cm . The wavelength of light is

Diffraction pattern of a single width 0.5 cm is formed by a lens of a focal length 40 cm. Calculate the distance between the first dark and next bright fringe from the axis. lambda = 4890 overset@A (given)

In an experiment with Fresnel biprism sodium light is used and bands 0.0196 cm in width are observed at the distance of 100 cm from the slit. A convex lens is placed between the biprism and the slit. If the distance between the slit and screen is one meter, the magnified distance apart of the images is found to be 0.7 cms, the lens being 30 cm from the slit, calculate the wavelength of light.
