In Young's experiment, two coherent sources are `1.5 mm` apart and the fringes are obtained at a distance of `2.5 m` from them. If the sources produce light of wavelength `589.3 nm`, find the number of fringes in the interference pattern, which is `4.9 xx 10^(-3) m` long.

In Young's double slit experiment the coherent sources are 1.5 mm apart and the fringes are obtained on a screen at a distance 2.5 m from the plane of the sources. If the sources is illuminated with a light of 589.3 nm wavelength , find the number of fringes in the interference pattern thus formed on the screen. Total length of the fringes are 4.9 xx 10 ^(-3) m.

In a Young's experiment,two coherent sources are placed 0.9 mm apart and the fringes are observed 1 m away.If it produces the second dark fringe at a distance of 1 mm from the central fringe,the wavelength of monochromatic ligth used would be

Two coherent sources are 0.15 mm apart and fringes are observed 1m away with monochromatic light of wavelength 6000^(0) . Find The fringe width in a liquid of refraction index 5"/"2 .

In a Young's experiment, two coherent sources are placed 0.90mm apart and the fringes are observed one metre away. If is produces the second dark fringe at a distance of 1mm from the central fringe, the wavelength of monochromatic light used would be
