- 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 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 The shorter wavelength blue light is, however, scattered all around the sky and whichever direction we look, some of this scattered blue light enters our eyes Hence sky appears blue to us
- Why does the sky appear blue - Toppr
A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight
- Why does sky appears blue - BYJUS
Why does sky appears blue ?The correct option is D Fine particles in the air scatter blue light more than red light 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 lights of shorter wavelengths at the blue end than light of longer wavelengths at the red end The red light has a wavelength about 1 8 times greater than blue light Thus, when sunlight passes through the atmosphere, the
- 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 enters our eyes Since we see the blue light from everywhere overhead, the sky appears blue
- 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 ? Explain. - Toppr
Violet colour is scattered the most followed by blue, green, yellow, orange and red colours respectively Our eye is more sensitive to the blue light than the violet light Therefore, scattered light in the sky contains blue colour in plenty and hence the clear sky appears blue Note : Sky appears greyish over cities having industrial units
- Why does Sky appear Blue ? Which phenomenon explains the appearance
The correct option is D Scattering Sky looks blue due to Scattering of light from the dust particles Molecules in the air scatter blue light from the sun more than they scatter red light When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight
- Why do clouds appear white while sky appears blue? - BYJUS
Q Why do clouds appear white while sky appears blue? Q Clouds are white because of light scattering off of water droplets Q Match the following statements with correct terms associated with it Statement Options (A)Light makes tiny particles visible due to (1)Scattering scattering
- 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 atmosphere that can refract the light
