- Scattering of light - BYJUS
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 Mie effect Due to the largeness of particles, the light appears white That is why the clouds, which are made of water droplets, are white
- Some Natural Phenomena Due To Sunlight - BYJUS
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 particles In the spectrum of white light, blue is the colour that has a minimum wavelength Hence, the blue colour scatters the most and is scattered in all directions by the tiny atmospheric particles This is the reason why the sky appears blue Reddish Sunset and Sunsets At sunrise or sunset
- Assertion :Blue colour of sky appears due to scattering of . . . - Toppr
Scattering of sunlight through molecules of atmosphere is the reason for the blue of the sky Our atmosphere contains atoms and molecules of different sizes 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 frequencies which are lower than the frequency of blue light Blue colour scatters more than other colours That is why sky appears
- Distinguish between sky wave and space wave modes of . . . - Toppr
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?

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 4 English solutions for free from the links given below
- Why sky wave propagation is not possible high frequency radio . . . - Toppr
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 opaque at all The power will transmit out to space ,which is not we want It would not let sky waves propagate it will just head out into space
