Find the angular separation between the consecutive bright fringes in a Young’s double slit experiment with blue-green light of wavelength 500 nm. The separation between the slits is 2.0 × 10^-3 m.

In a double slit interference experiment, the separation between the slits is 1.0 mm, the wavelength of light used is 5.0 × 10^-7 m and the distance of the screen from the slits is 1.0 m. (a) Find the distance of the center of the first minimum from the center of the central maximum. (b) How many bright fringes are formed in one centimeter width on the screen?

In a Young’s double slit experiment, two narrow vertical slits placed 0.800 mm apart are illuminated by the same source of yellow light of wavelength 589 nm. How
far are the adjacent bright bands in the interference pattern observed on a screen 200 m away?

A source emitting light of wavelengths 480 am and 600 nm is used in a double slit interference experiment. The separation between the slits is 0.25 mm and the interference is observed on n screen placed at 150 cm from the slits. Find the linear separation between the first maximum next to the central maximum) corresponding to the two wavelengths.

White light is used in a Young’s double slit experiment. Find the minimum order of the violet fringe (λ = 400 nm) which overlaps with a red fringe (λ = 700 nm).
