The magnetic field in a plane electromagnetic wave is given by `B_(y) = 2xx10^7 T sin (0.5xx10^3x+1.5xx10^11 t) T`
(a) What is the wavelength and frequency of the wave?
(b) Write an expression for the eletric field.

Explanation

To solve the given problem, we will follow these steps:

### Part (a): Finding the Wavelength and Frequency

1. **Identify the given magnetic field equation:**
\[ B_y = 2 \times 10^7 \, \text{T} \sin(0.5 \times 10^3 x + 1.5 \times 10^{11} t) \]
