A electromagnetic wave in vacuum has the electric and magnetic fields E → and B → which are always perpendicular to each other. The direction of polarization is given by X → and wave propogation by K → then

X → ∥ E → and K → ∥ E → × B →

X → ∥ B → and K → ∥ E → × B →

X → ∥ E → and K → ∥ B → × E →

X → ∥ B → and K → ∥ B → × E →

Magnetic field in a plane electromagnetic wave is given by, B → = B 0 sin k x + ω t j ^ T . Expression for corresponding electric field will be: (Where c is speed of light)

E → = B 0 c sin k x + ω t k ^ V m - 1

E → = - B 0 c sin k x + ω t k ^ V m - 1

E → = B 0 c sin k x - ω t k ^ V m - 1

E → = B 0 c sin k x + ω t k ^ V m - 1

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

For an electromagnetic wave propagating in + x direction the electric field is E → = 1 2 E y z x , t y ^ - z ^ and the magnetic field is B → = 1 2 B y z x , t y ^ + z ^

For an electromagnetic wave propagating in + y direction the electric field is E → = 1 2 E y z x , t z ^ and the magnetic field is B → = 1 2 B z x , t y ^

For an electromagnetic wave propagating in + y direction the electric field is E → = 1 2 E y z x , t y ^ and the magnetic field is B → = 1 2 B yz x , t z ^

For an electromagnetic wave propagating in + x direction the electric field is E → = 1 2 E y z y , z , t y ^ + z ^ and the magnetic field is B → = 1 2 E y z y , z , t y ^ + z ^
