The image shows a calculation to determine the speed of light in a medium based on its refractive index.

### Formula:
The speed of light in a medium \( v \) is related to the speed of light in free space \( c \) and the refractive index \( n \) of the medium by the equation:
\[
v = \frac{c}{n}
\]

In the image:
- The speed of light in free space \( c \) is \( 3 \times 10^8 \ \text{m/s} \).
- The refractive index of the core \( n \) is 1.5.

So, the speed of light in the core (or the medium) is calculated as:
\[
v = \frac{3 \times 10^8}{1.5} = 2 \times 10^8 \ \text{m/s}
\]

### Conclusion:
The speed of light in the core is \( 2 \times 10^8 \ \text{m/s} \).

2. How does the speed of light change when moving from one medium to another?
3. What factors can affect the refractive index of a material?
4. Can the refractive index of a material be less than 1? Why or why not?
5. How is the refractive index measured experimentally?

**Tip:** In optical fibers, the refractive index of the core material plays a critical role in determining how light propagates through the fiber.
