The electric field of an EM wave pulse traveling along the $x$ axis in free space is given by $E_{y}=E_{0} \exp \left[-\alpha^{2} x^{2}-\beta^{2} t^{2}+2 \alpha \beta x t\right],$ where $E_{0}, \alpha,$ and $\beta$ are positive constants, (a) Is the pulse moving in the $+x$ or $-x$ direction? (b) Express $\beta$ in terms of $\alpha$ and $c$ (speed of light in free space). (c) Determine the expression for the magnetic field of this EM wave.
