Why does the Sun appear red at sunrise?

उत्तर
- At sunrise or sunset, the Sun and its surroundings appear red due to light scattering.
- At the time of sunset or sunrise, the light rays from the sun have to travel a long distance to reach our eyes through the Earth’s atmosphere.
- In other words, we can say that when we look towards the horizon, we are looking through more of Earth’s atmosphere than when we look overhead.
- The light reaching our eyes is rich in red colour, as blue light is largely scattered by the particles in Earth’s atmosphere.
