A broad sources of light of wavelength `680nm`illuminated normally two glass plates.`120nm`long that meet at one end and are separated by a wire`0.048mm`in diameter at the other end,Find the number of bright fringes formed over the `120nm`distance.

Light wavelength 650 nm is incident normally upon a glass plate the glass plate rests on top of second plate so that hey touch at one end and are separated by 0.0325 mm at the other end as shown in the figure. Which range of values contains the horizontal separation between adjacent bright fringes?

Laser light of wavelength 630 nm incident on a pair of slits prodeuces an interference pattern in which the bright fringes are separated by 8.3 mm .A second light produces an interfernce pattern in which the bright fringes are separated by 7.6 mm .Find the wavelength of the second light.

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?
