Distinguish between 'sky wave' and 'space wave' modes of propagation. According to their sizes they are able to scatter different wavelength of light. When sunlight enters the earth’s atmosphere, it gets scattered by the atmospheric.

Atmospheric optics is the scientific study and explanation of the unique and stunning optical effects in the sky. For example, the size of the water molecule is greater than the size of the n 2 or o2 it acts as scattering centre for other. Why is the sky wave mode of propagation restricted to frequencies upto 40 m h z?

In a cloud, sunlight is scattered by much larger water droplets. Blue sky it is normal to say that the sky appears blue in colour. When the sun rays enter the earth, they get distorted by the earth’s atmosphere including air molecules, dust and smoke. Molecules with a larger size than the wavelength of light experience the scattering effect differently;
Have you ever thought about why it appears blue? Hence, the sky appears dark to passengers flying at high altitudes. It encompasses the principles of physics that help answer common questions like why the. The phenomenon is known as.
Why does the sunlight appear red, orange or yellow?
Why is the colour of the clear sky blue? The correct option is d scattering the sky looks blue due to the scattering of light by the molecules of air as blue light is scattered more than the red light due to its shorter wavelength. These scatter all colours almost equally meaning that the sunlight continues to remain white and so making the clouds. And why are the clouds white?
∙ at a higher altitude, the atmospheric medium is very rarer so the scattering of light taking place is very low.
