A viewing screen is separated from a double slit by 1.1 m. The distance between the two slits is 0.035 mm. Monochromatic light is directed toward the double slit and forms an interference pattem on the screen. The second-order bright-fringe (m = 2) is 4.25 cm from the center of the screen. Helpful Equations: (1) yrigir =L tan 6rein (2) d sin eign = m2(m= 0,±1,±2, ..) (3) sin ở = tan 8 (Small-angle approx.) || 100 cm = 1 m || 1000 mm = 1 m || 10° m= 1 nm (a) Determine the wavelength of light (in nanometer.)
