In a biprism experiment, the distance between 4th an 13th bright fringes is measured when light of wavelength `6 xx 10^(-7)` m is used. On replaceing the source by another of different wavelength without disturbing the adjustment of the apparatus , it is found that the distance between 5th and 15th bright fringes is the same as measured before, what is the wavelength of light used?

In a biprism expeirment the distance between the thrid and thirteenth dark fringes on the same side of central bright fringe is y when light of wavelenght 5400Å is used. On replacing the source by another of a differnet wavleneght, without distrubing the adjustment of the appartus it is found tht the distance between the fourth and thirteenth dark fringes on the same side of the central bright fringe is the same as y. The wavelenght of ligh used in the second case is

In a biprims experiment, the distance between the 3rd and 12th bright bands when light of wavelength 6000Å is used is the same as the distance between 4th and 14 th bright bands of light of wavelength lamda . The value of lamda is

In a biprism experiment, the distance between the first and eleventh bright fringes formed by light of wavelength lambda is 1.8 xx 10^(-3) m. If the light is replaced by one width wavelength 0.8 lambda , find the distance between the first and sixteenth bright fringes.

In a biprism experiment, the distance of the 7th dark band from the central bright band is 2.6 mm. the width of the fringe is

With two slits spaced 0.2 mm apart and a screen at a distance of 1 m, the third bright fringe is found to be at 7.5 mm from the central fringe. The wavelength of light used is

In Young's double slit experiment, the distance between the slits is 1 mm and that between slit and screen is 1 meter and 10th fringe is 5 mm away from the central bright fringe, then wavelength of light used will be

The distance between two coherent sources is 1 mm. The screen is placed at a distance of 1 m from the sources. If the distance of the third bright fringe is 1.2 mm from the central fringe, the wavelength of light used is

In a double slite experiment, the distance between the slit is 0.05 cm and screen is 2 m away from the slits. The wavelength of light is 6xx10^(-5) cm. The distance between the two successive bright fringes is
