Suppose that the electric field amplitude of an electromagnetic wave us `E_0=120 N// C` and that its frequency is `50.0 MHz`.
(a) Determine` B_0,omega,k` and `lambda`,
(b) find expressions for `E` and `B`.

Explanation

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

### Part (a): Determine \( B_0, \omega, k, \) and \( \lambda \)

1. **Given Data:**
- Electric field amplitude: \( E_0 = 120 \, \text{N/C} \)
- Frequency: \( f = 50.0 \, \text{MHz} = 50.0 \times 10^6 \, \text{Hz} \)
