Tom tried to measure the wavelength of light from a laser pointer with unknown specifications. He sent the laser through two very small slits and observed bright-dark fringes on the wall 2 meters from the slits. The distance between two neighboring bright lines in the center was measured to be 1 mm and the distance between two slits was also measured to be 1 mm. What is the laser wavelength
