-0.6

The electric field component of a uniform plane electromagnetic wave propagating in the $$Y$$-direction in a lossless medium will satisfy the equation

$${{{\partial ^2}{E_y}} \over {\partial \,{y^2}}} = \mu \in {{{\partial ^2}{E_y}} \over {\partial \,{t^2}}}$$

$${{{\partial ^2}{E_y}} \over {\partial \,{x^2}}} = \mu \in {{{\partial ^2}{E_y}} \over {\partial \,{t^2}}}$$

$${{{\partial ^2}{E_x}} \over {\partial \,{y^2}}} = \mu \in {{{\partial ^2}{E_x}} \over {\partial \,{t^2}}}$$

$${{\sqrt {E_x^2 + E_z^2} } \over {\sqrt {H_x^2 + H_z^2} }} = \sqrt {\mu / \in } $$
