# How are electromagnetic waves usually drawn?

May 22, 2017

See below.

#### Explanation:

From the diagram we can see how to draw a EM wave , Now how to analyse the direction of oscillation and direction of wave we need to form the wave equations.

${E}_{x} = {E}_{o} \sin \left(\omega t - k z\right)$
${B}_{y} = {B}_{o} \sin \left(\omega t - k z\right)$

when electromagnetic wave travel in space electric and magnetic field both are perpendicular to each other ,and the direction of motion of wave is given by $E \times B$
