You set up a double-slit experiment using a red laser that emits light with a wavelength of 521 nm that shines onto a pair of thin slits of unknown separation. On a screen placed 2.75 meters away from the slits, the first order maximum is found to be 3.42 mm from the central bright order. If we double the slit separation to twice its original (unknown) value, how far from the central bright order will the first order maximum now be located? (Give your answer in units of millimeters and round it to two decimal places.)
