A sinusoidal electromagnetic plane wave travels through empty space in the x-direction. The electric wave is polarized (plane of vibration in single plane) in the y-direction. Frequency of wave is 1.5 GHz. At a certain point P in space, the oscillating electric field `E_y ` attains a maximum magnitude `E_0 = 63` V/m.
What is the maximum magnitude `B_0` of the magnetic field at the same point? What is the direction of B?

Explanation

To find the maximum magnitude of the magnetic field \( B_0 \) at point P, we can use the relationship between the electric field \( E \) and the magnetic field \( B \) in an electromagnetic wave. The relevant equations and steps are as follows:

### Step-by-Step Solution:

1. **Identify the given values:**
- Frequency \( f = 1.5 \, \text{GHz} = 1.5 \times 10^9 \, \text{Hz} \)
- Maximum electric field \( E_0 = 63 \, \text{V/m} \)
