Explanation:
Speed of Light in Different Substances:
- Light travels at different speeds in different substances due to their varying optical properties.
- The speed of light in a medium is determined by its refractive index, which is a measure of how much the speed of light is reduced in that medium compared to its speed in a vacuum.
Why Water:
- In the given options, water has the fastest speed of light compared to turpentine, kerosene, and diamond.
- Water has a refractive index of approximately 1.33, which means light travels at about 225,000 km/s in water.
- This is faster than in turpentine, kerosene, and diamond because they have higher refractive indices which slow down the speed of light.
Refractive Index:
- The refractive index of turpentine is around 1.47, kerosene is around 1.45, and diamond is around 2.42.
- Higher refractive indices indicate slower speeds of light in those substances.
Conclusion:
- Therefore, in the given options, water allows light to travel the fastest due to its lower refractive index compared to the other substances.
- Understanding the speed of light in different materials is essential for various applications in optics, materials science, and engineering.
