Explanation:
Speed of Light in Different Mediums:
- The speed of light can vary depending on the medium it is traveling through. In a vacuum, light travels at a speed of approximately 299,792 kilometers per second.
- When light enters a different medium, such as glass, its speed changes due to the change in the medium's refractive index.
Dispersion of Light:
- When white light enters a medium like glass, it undergoes dispersion, separating into its constituent colors. This is why we see rainbows when light passes through water droplets in the atmosphere.
- The colors of light, such as orange and yellow, have different wavelengths and frequencies, causing them to travel at different speeds in a medium like glass.
Speed of Orange and Yellow Light:
- In general, shorter wavelengths (like blue and violet light) tend to travel slower in a medium compared to longer wavelengths (like red, orange, and yellow light).
- This is due to the interaction between the light waves and the atoms in the medium, which can cause different colors to be refracted at different angles and speeds.
Conclusion:
- Therefore, based on the principles of optics and the behavior of light in different mediums, we can determine that orange light and yellow light do not travel at the same speed in glass. Orange light, being closer to red light in the spectrum, would generally travel faster than yellow light in a medium like glass.
