When light travels into a material with a high index of refraction, its speed decreases.

Here's the step-by-step explanation:

1. **Understanding the Index of Refraction**: The index of refraction (n) of a material is a measure of how much the speed of light is reduced inside the material compared to its speed in a vacuum.

2. **Speed of Light in a Vacuum**: The speed of light in a vacuum is approximately $3 \times 10^8$ meters per second.

3. **Relation Between Speed and Index of Refraction**: The speed of light in a material (v) is given by the equation $v = \frac{c}{n}$, where $c$ is the speed of light in a vacuum and $n$ is the index of refraction of the material.

4. **High Index of Refraction**: When the index of refraction is high, it means that the material is optically dense, and light travels slower in it.

5. **Conclusion**: Therefore, when light enters a material with a high index of refraction, its speed decreases.
