Question

4. (a) Light from a helium-neon laser (630 nm) is incident on a pair of slits. In the interference pattern on a screen 1.5 m from the slits, the bright fringes are separated by 1.35 cm. What is the slit separation? (b) A second light source, when incident on the same pair of the slits, produces an interference pattern on the same screen with a separation of 1.02 cm between adjacent bright fringes at the center of the pattern. What is the wavelength of the second source?
