In two separate set-ups of YDSE, using light of same wavelength, fringes of equal width are observed. If ratio of slit separation in the equal width are observed. If ratio of slit separation in the two is `2:3`, the ratio of the distance between source and screen in the two set-ups is

In two separate set-ups of the Young's double slit experiment, fringes of equal width are observed when lights of wavelength in the ratio of 1:2 are used. If the ratio of the slit separation in the two cases is 2:1 , the ratio of the distance between the plane of the slits and the screen in the two set-ups are

State two conditions to obtain sustained interference of light. In young's double slit experiment, using light of wavelength 400 nm, interference fringes of width X are obtained. The wavelength of light is increased to 600 nm and the separation between the slits is halved. if one wants the observed fringe width on the screen to be the same in the two cases, find the ratio of the distance between the screen and the plane of the slits in the two arrangements.
