The correct Answer is:
To determine the speed of light, we can follow these steps: 1. **Understand the Concept of Speed of Light**: The speed of light refers to how fast light waves travel through different mediums. It is important to recognize that this speed can vary depending on the medium (like air, water, or vacuum). 2. **Identify the Speed of Light in a Vacuum**: The speed of light is most commonly referenced in a vacuum because it is the fastest speed at which light can travel. 3. **State the Value**: The speed of light in a vacuum is approximately \(3 \times 10^8\) meters per second (m/s). 4. **Conclusion**: Therefore, the speed of light is equal to \(3 \times 10^8\) m/s.
