Every EM wave has certain frequency. Name two parameters of an em wave that oscillate with this frequency.

Explanation

To answer the question regarding the two parameters of an electromagnetic (EM) wave that oscillate with its frequency, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding EM Waves**: Electromagnetic waves consist of oscillating electric and magnetic fields that propagate through space. These waves travel at the speed of light (denoted as 'c').

2. **Identify the Parameters**: The two primary parameters of an EM wave that oscillate are:
- **Electric Field (E)**: This field oscillates in a direction perpendicular to the direction of wave propagation.
