If the magnitude of the electric field of an electromagnetic wave in a medium is given by {\E}=10^{-7} \sin (6 \times 10^5 {\t}-0.01 x) {\N} {\C}^{-1}, then the frequency and speed of the electromagnetic wave respectively are (In the equation x is in metre and time t is in second)

Correct Answer is : 3×105πHz,6×107m s−1

\frac{6 \times 10^3}{\pi} {\Hz}, 3 \times 10^7 {\m} { s}^{-1}

\frac{3 \times 10^5}{\pi} {\Hz}, 6 \times 10^7 {\m} { s}^{-1}

\frac{3 \times 10^5}{\pi} {\Hz}, 3 \times 10^7 {\m} { s}^{-1}

\frac{6 \times 10^5}{\pi} {\Hz}, 6 \times 10^7 {\m} { s}^{-1}
