The correct Answer is:
To determine the true statement regarding primary and secondary rainbows, we will analyze the characteristics of both types of rainbows step by step. ### Step-by-Step Solution: 1. **Understanding Primary Rainbow**: - The primary rainbow is formed by the refraction, reflection, and dispersion of sunlight in raindrops. - The order of colors in the primary rainbow is: Red, Orange, Yellow, Green, Blue, Indigo, Violet (ROYGBIV). - In this rainbow, red is on the outer edge and violet is on the inner edge. 2. **Understanding Secondary Rainbow**: - The secondary rainbow is formed by two reflections of light inside the raindrops. - The order of colors in the secondary rainbow is reversed compared to the primary rainbow: Violet, Indigo, Blue, Green, Yellow, Orange, Red (VIBGYOR). - In this rainbow, violet is on the outer edge and red is on the inner edge. 3. **Comparing Intensity of Colors**: - The intensity of colors in the primary rainbow is greater than that in the secondary rainbow. This is due to the fact that light undergoes one reflection in the primary rainbow, while it undergoes two reflections in the secondary rainbow, which causes more light to be lost. 4. **Final Analysis of Statements**: - The first statement claims that the order of colors in the primary and secondary rainbow is the same. This is false; they are reversed. - The second statement claims that the intensity of colors in the primary and secondary rainbow is the same. This is also false; the primary rainbow is more intense. - The third statement claims that the intensity of the primary rainbow is greater than that of the secondary rainbow. This is true. - The fourth statement claims that the order of colors is the same. This is false; they are reversed. 5. **Conclusion**: - The true statement is that the intensity of colors in the primary rainbow is greater than that in the secondary rainbow. ### Final Answer: The correct statement is: "The intensity of colors in the primary rainbow is greater than that in the secondary rainbow."
