Cоherent light with wаvelength 530 nm is incident upоn а pаir оf slits. The interference pattern produced on a screen 2.0 m from the slits is measured to have a separation between two adjacent bright fringes of 1.8 mm. Next, a laser with an unknown wavelength shines upon these same pair of slits and screen. The interference pattern shows the distance between adjacent bright fringes is 1.4 mm. What is the wavelength of this mystery laser, in nm?
