The oscillating magnetic field in a plane electromagnetic wave is given by `B_y = ( 8 xx 10^(-6) ) sin [ 2xx 10^(11) t+ 300 pi x ] T `
(i) Calculate the wave length of the electromagnetic wave..
(ii) Write down the expression for the oscillating electric field.

Explanation

To solve the given problem, we will break it down into two parts as specified in the question.

### Part (i): Calculate the wavelength of the electromagnetic wave.

1. **Identify the given magnetic field equation**:
The oscillating magnetic field is given by:
\[
B_y = (8 \times 10^{-6}) \sin(2 \times 10^{11} t + 300 \pi x) \, \text{T}
