JEE Main 2016 Physics question

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

(1)For an electromagnetic wave propagating in direction the electric field is and the magnetic field is
(2)For an electromagnetic wave propagating in direction the electric field is and the magnetic field is
(3)For an electromagnetic wave propagating in direction the electric field is and the magnetic field is
(4)For an electromagnetic wave propagating in direction the electric field is and the magnetic field is Correct

Answer: (4)

Solution

Three requirements must all be met: the fields must be transverse (both perpendicular to the direction of travel), and must be perpendicular to each other, and must point along the direction of propagation. For a wave travelling along , the fields must also depend only on
