In the propagation of electromagnetic waves the angle between the direction of propagation and plane of polarisation is

Options

A. `0^(@)`
B. `90^(@)`
C. `45^(@)`
D. `80^(@)`

Answer

A

Explanation

Plane of vibration is perpendicular to the direction of propagation and also perpendicular to plane of polarisation. Thus, the angle between plane of polarisation and direction of vibration is `0^(@)` i.e. they are parallel.
