In a two-slit experiment, the slit separation is 3.00 × 10-5 m. The interference pattern is recorded on a flat screen that is 2.00 m away from the slits. If the seventh bright fringe on the detector is 10.0 cm away from the central bright fringe, what is the wavelength of the light passing through the slits?

The x-component of the electric field of an electromagnetic wave traveling in the +y-direction through vacuum is described by the equation Ex=(871 N/C) cos. What is the angular frequency of this wave? Give your answer in units of 1015 rad/s and round to `t` decimal places. c=3.00 x 108 m/s
