Which of the following statements is true when we see 'rainbow'? (1) We face sun and raindrops (3) 11 Km/Sec. (3) In light rainfall, we face Sun (4) The sky remains clear and the sun is at lower position in the sky
by

1 Answer

Answer :

(3) 11 Km/Sec. Explanation: We see rainbows because of the geometry of raindrops. When the sun shines from behind us into the rain, incident rays of light enter the drop and are refracted inwards. They are reflected from the back surface of the raindrop, and refracted again as they exit the raindrop and return to our eyes. A rainbow is an optical and meteorological phenomenon that is caused by reflection of light in water droplets in the Earth's atmosphere, resulting in a spectrum of light appearing in the sky.

Rainbow is produced in the sky after rainfall and sunlight.

Description : Rainbow is produced in the sky after rainfall and sunlight.

Last Answer : Ans: After rain, many droplet of water travel in the atmosphere. When sun rays fall on these droplets, dispersion of water occurs and droplets act as prism and produce a spectrum of seven colours. That’s why a rainbow is seen in the sky after rain.
