Coherent yellow light with a wavelength of 571 nm and coherent green light with a wavelength of 511 nm are incident on a double slit with slit separation of 0.0221 mm. The interference pattern is displayed on a screen 68.4 cm away.

(a) Find the separation between the m = 1 interference maxima of the two colors.

mm

(b) What is the separation between the m = 2 maxima for the two beams?

mm

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
