The electric field of an electromagnetic wave in free space is given by:
\({E=10 \cos \left(10^{7} t+k x\right) V / m}\)
where \({t}\) and \({x}\) are in seconds and metres, respectively. It can be inferred that
(a) the wavelength \({\lambda}\) is \(188.4\,m\)
(b) the wave number \({k}\) is \(0.33\,rad/m\)
(c) the wave amplitude is \(10\,V/m\)
(d) the wave is propagating along \({+x}\)-direction.
Which one of the following pairs of statements is correct?
