Which of the following are conditions necessary for observing rainbow?
Which of the following are conditions necessary for observing rainbow?
- A. The Sun should be behind us
- B. It should have rained and the sun should be present.
- C. None of A and B
- D. Both A and B
Step-by-step solution
For a rainbow, the sun must be behind the observer (so that sunlight is reflected and refracted by raindrops towards the observer) and there must be rain in front with sunlight present. Hence both conditions are necessary.
