In Lloyd's interference experiment, the path difference between direct and reflected beams of light for the 10th bright fringe was observed to be 0.63 mm. Find the wavelength of light used.

In Lloyd's experiment , the slit and its image have a separation of 4.32 mm and the obsevations made at a plane 2.0 m away fringes of separation 0.26 mm. Find the wavelength of light used.

In interference of light, a point is bright if the path difference between the two beams arriving at that point is

In a Young's double-slit experiment , the slits are separated by 0.28 mm and screen is placed 1.4 m away . The distance between the central bright fringe and the fourth bright fringe is measured to be 1.2 cm . Determine the wavelength of light used in the experiment .

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

In Young's double-slit experiment, monochromatic light of wavelength 630 nm illuminates the pair of slits prodcues an interference pattern in which two consecutive bright fringes are separated by 8.1 mm. Another source of monochromatic light produces the interference pattern in which the two consecutive bright fringes are separated by 7.2 mm. Find the wavelength of light for the second source. What is the effect on the interference fringes if the monochromatic source is replaced by a source of white light?

In a biprism experiment, the distance between the sit and the eyepiece is 1m and distance between the two coherent sources is 0.5 mm. If the wavelength of light used I 6000Å , then distance of the 10th bright and from the central bright band is

In Lloyd's interference experiment, 10 fringes occupy a space of 1.5 mm. The distance between the source and the screen is 1.25 m. If light of wavelength 6000 Å is used, find the distance of the source from the plane minor.
