The Sun’s Changing Colour

When we see the sun during the daytime it is like a bright yellow ball of fire but in the mornings and evenings we see it as a bright and glowing orange ball. In reality the Sun does not change it’s colour, this effect is produced by the earth’s atmosphere which acts as a light red filter. In the day time the Sun is high in the sky. It’s rays have to pass through a lesser part of the earth’s atmosphere, as a result of which the Sun is seen as a bright yellow ball of fire. During sunrise and sunset the rays have to pass through a larger part of the atmosphere, as shown in the diagram, thus giving the rays a reddish colour. This is the reason why the Sun appears red in colour during sunrises and sunsets. As we know light made up of different colours and rays of red light pass through air much more easily than rays of any other colour. All pictures of the Earth which are taken by satellites or by Astronauts in space, are usually taken through a red filter for this reason. (Never look at the sun directly or even through a lens, it could damage your eyesight).
