Light of wavelength 571 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 0.571 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 0.620 cm between adjacent bright fringes at the center of the pattern. What is the wavelength of the second source? (in nm) A: 620 B: 725 C: 849 D: 993 E: 1162
