A red laser pointer is emitting laser light in the + y direction having wavelength ) = 670 nm. The laser emits a 5.00 mW narrow circular beam with a diameter of 1:40 mm, polarized such that the electric field is along the xaxis. (a) [2 points] Determine the average intensity of the laser. (b) [2 points] Find the amplitude of the electric-field in the beam. (c) [2 points] Find the wavenumber of the light. (d) [2 points] Find the angular frequency of the light
