Multiple choice

If the electric field intensity associated with a uniform plane electromagnetic wave traveling in a perfect dielectric medium is given by E(z,t) = 10 cos (2$\pi$$\times$ 107t = 0.1$\pi$z) volt/m, then the velocity of the traveling wave is

  1. 3.00 $\times$ 108 m/sec
  2. 2.00 $\times$ 108 m/sec
  3. 6.28 $\times$ 107 m/sec
  4. 2.00 $\times$ 107 m/sec
