Assertion and Reasoning: Rainbow Formation
Assertion: A rainbow is sometimes seen in the sky in rainy season only when observer’s back is towards the sun.
Reasoning: Internal reflection in the water droplets cause dispersion and the final rays are in backward direction.
Explanation:
Rainbows are one of the most beautiful phenomena that occur in nature when sunlight is refracted, reflected, and dispersed in water droplets in the atmosphere. Let's understand the Assertion and Reasoning given in the question.
Assertion:
A rainbow is sometimes seen in the sky in the rainy season only when the observer's back is towards the sun.
Explanation:
When raindrops fall from the sky, they act as tiny prisms that refract and reflect sunlight. A rainbow is formed when sunlight is refracted, reflected, and dispersed in water droplets in the atmosphere. The observer can see the rainbow when the sun is behind them and the water droplets are in front of them. Thus, a rainbow is visible to an observer only when their back is towards the sun.
Reasoning:
Internal reflection in the water droplets cause dispersion, and the final rays are in the backward direction.
Explanation:
When sunlight enters a water droplet, it undergoes refraction and is dispersed into its individual colors. These colors are separated because of the difference in their wavelengths. The light is then reflected inside the water droplet, which causes internal reflection. Finally, the light exits the droplet and is refracted again as it travels from a denser medium to a rarer medium. This refraction causes the light to bend at an angle of 42 degrees, which is why we see a rainbow in the shape of an arc. The final rays of the rainbow are seen in the backward direction because they are reflected inside the raindrop and exit in the opposite direction to the incoming light.
Conclusion:
Hence, we can conclude that both the Assertion and Reasoning are true, and the Reasoning is the correct explanation of the Assertion.
