Homework Statement
There is no specific problem - this is more of a broad question...given a wave equation and asked to write down/guess an expression/general solution for a traveling wave, it is sufficient to say the following:
1) For [itex]\frac{\partial^2 E}{\partial z^2} - \frac{1}{c^2}*\frac{\partial^2 E}{\partial t^2}=0[/itex]
when asked to right down an expression for a traveling wave moving in the positive z direction with amplitude A is it sufficient to write [itex]E=A*sin(kz-\omega t)[/itex]
2) For [itex]\frac{\partial^2 E}{\partial z^2} - \frac{\epsilon}{c^2}*\frac{\partial^2 E}{\partial t^2}-\sigma*\mu*\frac{\partial E}{\partial t}=0[/itex]
when asked to guess a general solution for a traveling wave, it is sufficient to write [itex]E=A*sin(kz-\omega t)[/itex]
Please let me know if this sounds reasonable. Thank you for your time and help
