1,) Light that has a wavelength of 668 nm passes through a slit 6.73 multiply.gif 103 nm wide and falls on a screen that is 1.55 m away. What is the distance on the screen from the center of the central bright fringe to the third dark fringe on either side?

2,) A dark fringe in the diffraction pattern of a single slit is located at an angle of θA = 38^o. With the same light, the same dark fringe formed with another single slit is at an angle of θB = 62^o. Find the ratio WA/WB of the widths of the two slits.
