2. At a given point z, the electric fields of two electromagnetic waves in free space are given by the following equations: E₁ - 19 sin (wt +) V/m B₂ = 28 sin (wt +) V/m. (a) If = 6.28 x 10¹5 rad/s, what is the frequency and wavelength of the waves? What part of the electromagnetic spectrum is this in? (b) What are the amplitudes and phases of each wave? (c) What are the amplitude and phase of the superposition of the waves? (d) Provide the equation for the resultant wave. This should consist of a single term. It is most straightforward to use the formula sheet.
