Consider a circularly polarized electromagnetic plane wave propagating in vacuum in the z direction. Its electric field is given by Ē = EoRe(x+iy/√2. e^i(kz-ωt) where x and y are unit vectors and Eo, is a constant. Required:a. Write the x- and y-components of the electric field and show that it is indeed circularly polarized electromagnetic wave. b. Compute the Poynting vector and demonstrate that, unlike for the case of a linearly polarized plane wave it is independent of space and time. c. Calculate the energy density of this electromagnetic wave.

Which of the following correctly describes what happens when an atomic bomb explodes? small pieces of fissionable material are joined and form a body with a mass greater than the critical mass, the relative number of neutrons escaping decreases, and a chain reaction and explosion result. large pieces of fissionable matter are brought together quickly and form a body with a mass smaller than the critical mass, the relative number of escaping neutrons increases, and a chain reaction and explosion result.
