Pick the wrong statement in the context with a rainbow.

Question

Accepted Answer

1.  **Formation of Rainbow:** A rainbow is a natural spectrum appearing in the sky after a rain shower. It is caused by the dispersion, refraction, and **internal reflection** of sunlight by spherical water droplets acting as prisms.
2.  **Primary vs. Secondary:** 
    -   **Primary Rainbow:** Involves one internal reflection. Violet is on the inner edge and Red on the outer edge.
    -   **Secondary Rainbow:** Involves **two internal reflections** inside the droplet (Statement 2 is correct). Due to the extra reflection, the intensity of light is reduced, and the **order of colors is reversed** (Red is on the inner edge, Violet on the outer) (Statement 3 is correct).
3.  **Condition for Visibility:** For an observer to see a rainbow, the sun must be **behind** them. The observer must look away from the sun towards the rain. If the observer faces the sun, they cannot see the rainbow (Statement 4 is incorrect).
