In a biprism experiment, if the distance between the slit and the biprism is slightly increased, without disturbing the remaining setting, then the bandwidth will

In Fresnel's biprism experiment, when the distance between the slit aperture and eye is increased, then distance between the fringes

In a biprism expeirment , the distance between the slit and the biprism is 20 cm and the distance between the biprism and focal and plane of the epyepiece is 80 cm. Whith the separation between two virtual images of the slit seperation between two virtual images of the slit is 0.4 cm, an interfence pattern is obtained with a light of wavelength 5500Å .The distance between the third and eighth bands on the same side of the central bright band is

In a biprism experiment, to determine the distance between coherent sources, the convex lens is introduced

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 a biprism experiment, the distance (d) between the two sources is doubled and the distance between the slit and the eye piece is also doubled. Then the width of the fringe

In fresnel's biprism experiment the distance between the source and the screen is 1 ma nd that between the screen is 1 m and that between the source and biprism is 10 cm. the wavelength of light used is 6000Å. The fringe width obtained is 0.03 cm and the refracting angle of biprism is 1^(@) then calculate the refractive index of the material of biprism.
