Light of wavelength 665 nm is used to illuminate normally two glass plates 12 cm in length that touch at one end and are separated at the other end by a wire of radius 0.02 mm. How many bright fringes appear along the total length of the plates?
Assume that light of wavelength 550 nm is being observed. Also suppose that diffraction effects, rather than atmospheric turbulence, limit the resolving power of the telescope. Find the greatest distance that these stars might be from the earth.
