MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Light from a coherent monochromatic light source with a wavelength of 5.40 x 10" nm is incident on (and perpendicular to) a pair of slits separated by 0.290 mm. An interference pattern is formed on a screen 2.10 m from the slits. Find the distance (In mm) between the first and second dark fringes of the interference pattern. mm Need Help?

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A laser beam is normally incident on a single slit with width 0.560 mm. A diffraction pattern forms on a screen a distance 1.35 m beyond the slit. The distance between the positions of zero intensity on both sides of the central maximum is 2.32 mm. Calculate the wavelength of the light (in nm). nm Need Help? Read It Submit Answer 11.
