Why Is the Colour of the Clear Sky Blue? And Why Are the Clouds White? Molecules with a larger size than the wavelength of light experience the scattering effect differently; the phenomenon is known as …

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.

Blue Sky It is normal to say that the sky appears blue in colour. Have you ever thought about why it appears blue? When sunlight enters the Earth’s atmosphere, it gets scattered by the atmospheric …

According to their sizes they are able to scatter different wavelength of light. 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 …

Chapter 4 – Why? and Alice in Wonderland Solutions answers the questions related to each and every topic discussed in this chapter. Students can refer to and easily download the PDF of NCERT Class …

Distinguish between 'sky wave' and 'space wave' modes of propagation. Why is the sky wave mode of propagation restricted to frequencies upto 40 M H z?

The blue light due to its short wavelength is scattered more than the red light of long wavelength. Thus the light directly from the sun reaching our eye is rich in red colour while the light from all the other …

Sky wave propagation is not possible for high frequency radio waves because the atmosphere is opaque and will reflect signal well only for lower frequencies.At higher frequencies the atmosphere is not …

Atmospheric optics is the scientific study and explanation of the unique and stunning optical effects in the sky. It encompasses the principles of physics that help answer common questions like why the …

This is also the reason, why life is existing only on Earth at the moment. If one looks from the outer space, the earth appears blue. This is because, a 2/3rds surface of the earth, is covered by water. …
