प्रश्न
How are electric vector `(vec "E")`, magnetic vector `(vec "B")` and velocity vector `(vec "C")` oriented in an electromagnetic wave?
उत्तर
The electric field `(vec"E")`, magnetic field vector `(vec "B")` and velocity vector `(vec"C")` are mutually perpendicular to each other.
`"E"/"B" = "C"`
