When we close one slit in the Young's double slit experiment, then

When both the slits are opened, we can see interference pattern. Why?

A beam of light consisting of two wavelengths, 6500 Å and 5200 Å is used to obtain interference fringes in a Young's double slit experiment (1 Å = 10^(-10) m). The distance between the slits is 2.0 mm and the distance between the plane of the slits and the screen in 120 cm. (a) Find the distance of the third bright fringes on the screen from the central maximum for the wavelength 6500 Å (b) What is the least distance from the central maximum where the bright fringes due to both the wavelengths coincide ?

In Young's double slit experiment, the slits are 2 mm apart and are illuminated with a mixture of two wavelength lamda_0 = 750 nm and lamda = 900 nm. What is the minimum distance from the common central bright fringe on a screen 2 m from the slits where a bright fringe from one interference pattern coincides with a bright fringe from the other?

In young's double slit experiment , the slits are 2mm apart and are illuminated by photons of two wavelength lambda_1=12000overset@A and lambda_2=10000 overset@A . At what minimum distance from the slit will a bright fringe from one interference pattern coincide with a bright fringe from the other?
