In a biprism experiment, when sodium light of wavelength 5890 Å is used then twenty fringes are observed in 23 mm distance on screen. In order to obtain 30 fringes in 28 mm of the interference pattern, one should use light of wavelength :

In a Fresnel's biprism experiment, sodium light of wavelength 5832 Å is used. Calculated the fringe width, given the distance between the screen and the biprism =120 cm and the distance the two sources=0.04 cm.

In Young's double slit experiment, when light of wavelength 4000 A^(@) is used 90 fringes are seen on the screen. When light of 3000 A is used, the number of fringes seen is

In Young's experiment when sodium light of wavelength 5893 Å is used 62 fringes are visible in the vision -field. How many fringes will be visible if violet light of wave length 4358 Å is used ?

In Young's experiment with a monochromatic light of wavelength 5890 Å , the slits are separated by a distance 1 mm. Find the angular width between two successive interference fringes.

In a YDSE setup sodium light of wavelength 5893 Å is being used. The interference pattern is obtained on a screen which is located at a distance 1 m from the slit plane. In the interference pattern it is observed that 10^(th) bright fringe is located at a distance of 12mm from the central maximum. Find the slit separation.
