Red colour of sun at the time of sunrise and sunset is because:

• A. red colour is least scattered.
• B. blue colour is least scattered.
• C. red colour is scattered the most.
• D. all colour are equally scattered.

Answer 1

The correct option is A red colour is least scattered.

During sunrise and sunset, the rays have to travel a larger part of the atmosphere because they are very close to the horizon. Therefore, light other than red is mostly scattered away. The red light, which is the least scattered, enters our eyes. Hence, the sun appear red during sunrise and sunset.
