Consider an electromagnetic wave propagating in vacuum. Choose the correct statement:

Options

  1. AFor an electromagnetic wave propagating in + y direction the electric field is E → = 1 2 E y z x , t z ^
  2. BFor an electromagnetic wave propagating in + y direction the electric field is E → = 1 2 E y z x , t y ^ and t
  3. CFor an electromagnetic wave propagating in + x direction the electric field is E → = 1 2 E y z y , &#160
  4. DFor an electromagnetic wave propagating in + x direction the electric field is E → = 1 2 E y z x , t &#1

Correct answer

D. For an electromagnetic wave propagating in + x direction the electric field is E → = 1 2 E y z x , t &#1

Step-by-step solution

Wave in x - direction means E → and B → should be function of x and t y ^ - z ^ ⊥ y ^ + z ^ E →   × B → | |   x ^
