Solution

For an electromagnetic wave electric and magnetic field is given by

$E_{X} = E_{O} S I N (K z - ω t) B_{Y} = B_{O} S I N (K z - ω t) w h e r e k i s r e l a t e d t o w a v e l e n g t h λ a s k = \frac{2 π}{λ} i t i s a l s o s e e n f r o m m a x w e l l' s e q u a t i o n s t h a t t h e m a g n i t u d e o f e l e c t r i c a n d m a g n e t i c f i e l d s i n a n e l e c t r o m a g n e t i c w a v e a r e r e l a t e d a s B_{O} = \frac{E_{O}}{C} W H E R E C I S T H E S P E E D O F E L E C T R O M A G N E T I C W A V E I N V A C C U M$
