Suppose that the electric field part of ...

Suppose that the electric field part of an electromagnetic wave in vacuum is `vec(E )={(3.1 N//C)cos [(1.8 rad//m)y+(5.4xx10^(6)rad//s)]}hat(i)`
What is the direction of propagation ?

Text Solution

Verified by Experts

Here equation of electric field has the form like `E = E_(0)cos (omega t+ky)` and so given wave must be propagating along Y axis. …..(1)
