In a two-slit experiment, the slit separation is 3.00 x 10-5 meter. The interference pattern is created on a screen that is 2 meter away from the slits. If the 7th bright fringe on the screen is a linear distance of 10 centimeter away from the central fringe, compute what is the wavelength of the light?
A parallel-plate air capacitor with a capacitance of 245 has the charge of magnitude 0.1502 on each plate. The plates have the separation of 0.323.
