A plane wave is described by ?(?,?) = A ei(2x+4y-5z-7t), where all numerical quantities are given in SI units. A) Determine a mathematical expression that describes the planes of constant phase (and therefore, a constant wave or a wavefront ) B) In which direction the planes of constant phase propagate? In other words, determine the components of the k-vector? C) What is the wavelength ? (make sure to provide proper unit) of this wave? D) What is the speed v that a plane with constant phase propagates (make sure to provide proper unit)? E) What is the frequency ? (make sure to provide proper unit)?
