Which of the following statements is true when we see 'rainbow' ?
- A. We face sun and raindrops
- B. The Sun remains behind us and we face raindrops
- C. In light rainfall, we face Sun
- D. The sky remains clear and the sun is at lower position in the sky
Explanation
A rainbow appears when sunlight is behind the observer and raindrops are in front, because the drops disperse, refract, and internally reflect the light toward the observer. Facing the Sun places the rainbow generally behind the observer.
