A He–Ne laser beam is reflected from the surface of a CD onto a wall. The brightest spot is the reflected beam at an angle equal to the angle of incidence. However, fringes are also observed, at different angles of reflection. The wavelength of a He-Ne laser is λ = 633 nm. If the wall is 1.35 m from the CD, and the first fringe is 0.58 m from the central maximum, what is the spacing of grooves on the CD, in meters? d =
