A double-slit arrangement produces interference fringes for sodium light (`lambda= 589 nm`) that are `0.20^@` apart. What is the angular fringe separation, if the entire arrangement is immersed in water. (n = 1.33)

a double - slit arrangement, the slits are separated by a distance equals to 100 times the wavelength of light passing through the slits:- What is the angular separation in radians between the central maximum and an adjacent maximum?

In double-slit experiment using light of wavelength 600 nm, the angular width of a fringe formed on a distant screen is 0.1^@ . What is the spacing between the two slits ?

In Young's double slit experiment , the fringe width is found to be 0.4 mm . If the whole apparatus is dipped in water of refractive index 4/3 . Without disturbing the arrangement , the new fringe width will be

Two straight and narrow parallel slits separated by 3mm are illuminated by a monochromatic light of wavelength 5460 overset (@)(A) . Interference fringes are obtained at a distance of 60 cm from the slits. Find the change in fringe width if the distance between the slits is i) increased by 1 mm and ii) decreased by 1mm.

Monochromatic light from a narrow slit illuminates two narrow slit 0.3 mm apart producing an interference pattern with bright fringes 1.5 mm apart on a screen 75 cm away. Find the wavelength of the light. How will the fringe width altered if the distance of the screen is doubled .

In a double -slit arrangement the slits are separated by a distance equal to 100 times the wavelength of the light passing through the slits. What is the distance between these maxima on a screen 50.0 cm from the slits ?

a double - slit arrangement, the slits are separated by a distance equals to 101 times the wavelength of light passing through the slits:- What is the distance between these maxima on a screen 50.0 cm from the slits?

In Young's double slit experiment the slits are 0.5 mm apart and interference is observed on a screen placed at a distance of 100 cm from the slits. It is found that the 9th bright fringe is at a distance 8.835 mm from the second dark fringe from the centre of the fringe pattern. Find the wavelength of light used.
