1. How many colours are there in a rainbow?**Answer:** There are seven colours commonly identified in a rainbow: red, orange, yellow, green, blue, indigo, and violet. However, the spectrum is actually continuous, with a gradual blending of colours.2. What is the last colour of rainbow?**Answer:** Violet3. Is there blue in the rainbow?**Answer:** Yes4. What can you often see in the sky after rain?**Answer:** A rainbow (and sometimes a double rainbow)5. How does the rainbow look on us?**Answer:** A rainbow appears as a multi-coloured arc in the sky. Its exact appearance depends on the observer's position relative to the sun and the rain.6. Why can't you see the other half of a rainbow?**Answer:** You can't see the other half of a rainbow because the reflection and refraction of sunlight within raindrops only creates a visible arc at a specific angle relative to the observer and the sun. The other half of the circle is below the horizon and not visible to you.7. Where does the other half of the rainbow hide?**Answer:** The other half of the rainbow isn't "hidden" in a physical sense. It's simply not visible from your perspective on the ground. To see a more complete circle, you would need to be in a position such as an airplane, high above the ground.8. How are the colours of rainbow?**Answer:** The colours of a rainbow are arranged in a specific order based on the wavelengths of light. Red has the longest wavelength and violet the shortest. The colours blend smoothly into each other, forming a continuous spectrum.
