Wave behavior of light #5 EM Field and Photons

Показать описание
Light of wavelength 690 nm is incident on a single slit 0.71 mm wide. At what distance from the slit should a screen be placed if the second dark fringe in the diffraction pattern is to be 1.7 mm from the center of the diffraction pattern? Answer in m, with 3 significant figures.
Two slits in an opaque barrier each have a width of 18 micrometers and are separated by 55 micrometers. When coherent monochromatic light passes through the slits, what is the number of interference maxima within the central diffraction maximum?
