a) Consider a laser beam propagating through free space. The beam has an average power of 5 mW (a typical power for a handheld laser pointer) and is distributed over an area of 1 mm². Assuming that the electromagnetic wave associated with this beam can be described by a plane electromagnetic wave, approximate the magnitude of the electric field associated with this laser beam.
