Light of wavelength 565 nm incident on a pair of slits produces an interference pattern on a distant screen in which the separation between adjacent bright fringes at the center of the pattern is 0.569 cm. A second light source, when incident on the same pair of slits, produces an interference pattern on the same screen with a separation of 0.622 cm between adjacent bright fringes at the center of the pattern. What is the wavelength of the second source?
