1.	26. Give reasons:) Colour of the clear sky is blueil) Danger Signals are red
Answer» The colour of the clear sky is blue because molecules in the air scatter bluelightfrom the sun more than they scatterred light. When we look towards the sun at sunset, we seeredandorangecolours because the blue lighthas been scattered out and away from the line of sight. The primary reason why the colorredis used fordanger signalsis thatredlight is scattered the least by air molecules. The effect of scattering is inversely related to the fourth power of the wavelength of a color. Soredlight is able to travel the longest distance through fog, rain, and the alike.

Answer»

The colour of the clear sky is blue because molecules in the air scatter bluelightfrom the sun more than they scatterred light. When we look towards the sun at sunset, we seeredandorangecolours because the blue lighthas been scattered out and away from the line of sight.

The primary reason why the colorredis used fordanger signalsis thatredlight is scattered the least by air molecules.

The effect of scattering is inversely related to the fourth power of the wavelength of a color.

Soredlight is able to travel the longest distance through fog, rain, and the alike.
