Angular Width

If screen is shifted in x direction away from source then which of the following is incorrect? D Angular width of fringe does not change due to shifting Position of all maxima are changing Fringe width remains constant Central maxima is shifted along x-axis

In a double slit experiment the angular width of a fringe is found to be 0.2^(@) on a screen placed I m away. The wavelength of light used in 600 nm. What will be the angular width of the fringe if the entire experimental apparatus is immersed in water ? Take refractive index of water to be 4//3 .

A narrow slit is illuminated by a parallel beam of monochromatic light of wavelength lambda_(0) equals to 6000 A^(0) and the angular width of the central maxima in the resulting diffraction pattern is measured.When the slit is next illuminated by light of wavelength lambda ,the angular width decreases to half.Calculate the value of the wavelength lambda .

In a double slit experiment, when light of wavelength 400 nm was used, the angular width of the first minima formed on a screen placed 1 m away, was found to be 0.2^(@) , what will be the angular width of the first minima, if the entire experimental apparatus is immersed in water ? (mu_("water")=4//3)

In a Young's double slit experiment, light of 500 nm is used to produce an interference pattern. When the distance between the slits is 0.05 mm, the angular width (in degree) of the fringes formed on the distance screen is close to:
