Two thin parallel slits that are 0.012 mm apart are illuminated by a laser beam of wavelength 650 nm. On a very large distant screen, the total number of bright fringes including the central fringe and those on both sides of it is

Two parallel slits 0.6mm apart are illuminated by light source of wavelength 6000Å . The distance between two consecutive dark fringe on a screen 1m away from the slits is

Two slits 0,125 mm apart are illuminated by light of wavelength 4500 Å . The screen is 1m away, from the plane of the slits. Find the separation between the 2nd bright fringe on both sides of the central maximum.

Two slits, 4 mm apart, are illuminated by light of wavelength 6000 Å . What will be the fringe width on a screen placed 2 m from the slits

Two slits, 4 mm apart, are illuminated by light of wavelength 6000 Å . What will be the fringe width on a screen placed 2 m from the slits

In the Young.s double slit experiment , two slits 0.125mm apart are illuminated by light of wavelength 4500@A . The screen is 1 m away from the plane of the slits. Find the separation between second bright fringes on both sides of central maxima.

Two slits 0.125 mm aprt are illuinated by igth of wavelength 4500 ^@A .The screen is one metre way from the plane of the slits.Find the separation between the second bright fringes on both sides of the central maximum.

In Young's double -slit experiment, the slits are 0.5 cm apart and screen is 1m away. The slits are illuminated by sodium light of wavelength 6890 Å . What will be the distance between 3^(rd) bright fringe on one side and 4^(th) bright fringe on other side of central fringe.

In YDSE, two slits are separated by 3 mm and illuminated by light of wavelength 480 nm . The screen is 2 m from the plane of slits. Calculate the separation between 8th bright fringe and 3rd dark fringe observed on the same side of central bright fringe.
