- 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
- Why does the sky appear blue? - Toppr
When a white light (from sun) enters the earth's atmosphere, it gets scattered away due to the atmospheric particles Since, blue colour has the minimum wavelength, so blue colour scatters the most and thus the sky appears blue
- Why does the sky appear blue on a day? - Toppr
The sky appears blue on a clear day because of the scattering of blue component of white sunlight by air molecules presents in the atmosphere When sunlight passes through the atmosphere, most of the longer wavelength lights do not get scattered much and hence pass straight through the atmosphere
- Why do the sky appears dark instead of blue to the astronauts? - BYJUS
There is no atmosphere in the outer space We see the sky blue because scattering happens due to the particles in the atmosphere The reason for scattering of light is the colloidal particles in the atmosphere which refract the light in different directions When the blue light is refracted, this light comes to our eyes and thus the sky appears
- Explain giving reason why the sky appears blue to an observer . . . - Toppr
Explain giving reason why the sky appears blue to an observer from the surface of the Earth What should the appearance of the sky be during the day for an astronaut staying in the international space station orbiting the Earth? State reason to justify your answer
- Why is the colour of sky blue? - Toppr
The molecules of air and other fine particles in the atmosphere have size smaller than the wavelength of visible light These are more effective in scattering light of shorter wavelength at the blue end than light of longer wavelengths at the red end When sunlight passes through the atmosphere, the fine particles in air scatter the blue colour more strongly than red The scattered blue light
- Why is the colour of the clear sky blue? - Toppr
Sky as such does not have any colour as such, but looks blue due to the maximum scattering of blue colour Air and water molecules in the sky scatter blue light more since the colour has more energy than colours like red and orange Light of shorter wavelength is scattered much more than light of longer wavelength
- Why does the sky appears blue during day time, red during . . . - Toppr
Sky appears blue during day time because the light of sun gets scattered and the most scattered light is blue, so the sky appears blue During the evening and early morning when the sun is not overhead but it is below the horizon, the only light that reaches our eye is red and hence the sky appears to be reddish in colour For an astronaut, the sky appears to be black because there is no
