A plane polarized monochromatic EM wave ...

A plane polarized monochromatic EM wave is traveling in vacuum along Z direction such that at t=`t_(1)` it is found th at the electric field is zero at a spatial point `z_(1)` The next zero that occurs in its neighborhood is at `z_(2)` The frequency of the electromagnetic wave is :

A

`(6xx10^(8))/(|Z_(2)-Z_(1)|)`

B

`(1)/(t_(1)+(|Z_(2)-Z_(1)|)/(3xx10^(8))`

C

`(3xx10^(8))/(|Z_(2)-Z_(1)|)`

D
