Скачать или смотреть Refractive Index Made Easy: Why N = C/V Is the Ultimate Formula in Optics

In this lesson, we unlock one of the most powerful relationships in optics:
  📌 N = C / V

You’ll discover how the refractive index (N) is directly connected to the speed of light in air (C) and the speed of light in any material (V). This formula gives deep insight into how and why light bends when entering glass, water, diamond, and other transparent media.

What we cover:

✅ The full definition of refractive index using speed ratios
✅ The connection between Snell’s Law and the speed-of-light formula
✅ Why light slows down in denser media
✅ How to compare air to glass, water, diamond, acrylic, and more
✅ A preview of real numerical examples that follow this segment

Perfect for students preparing for WAEC, NECO, JAMB, UTME, IGCSE, A-Level, and first-year university physics, this clip breaks down the formula clearly using everyday language.

If you’ve mastered sin i / sin r, now it’s time to understand the speed-based refractive index that makes optics truly click.
