An electromagnetic wave is travelling in vacuum along the horizontal or x-axis. It consists of an electric field of peak strength 2.1 x 10-5 V m-1 in the vertical direction or z-axis and a magnetic field.

a) Find what is its speed v?

b) Find the peak strength of the magnetic field component?

c) If the E were momentarily vertical (+z) and the velocity is in the +x direction, what direction is B at that instant?

d) Find the direction of E, B and v one half period later?

e) Find the magnitude of the associated Poyntingvector?
