This speech focuses on the scientific explanation of why sky appears blue. When the sunlight falls on the small particles present in the atmosphere, they scatter them in all directions. Since sunlight has seven colours, the blue is scattered more than other colours. This colour finally reached our eyes and we see the sky as blue. But for an atmosphere, the sky will appear dark due to absence of atmosphere.
