Q. Question 23. Why is the colour of the clear sky blue? Q. why is sky blue ? Wider dispersion of light cannot be the only reason of blue colour of sky ? Why only blue colour scatters the most ? Even though blue scatters the most, why not the other colours appear ? Q. why is the colour of clear sky blue.
Q. The sky is blue due to the fact that is scatters the component of light which have shorter wavelength such as blue. However violet and indigo have even shorter wavelengths than hat of blue Then why is the sky either violet or indigo in color? Q. Assertion :Bluish colour predominates in a clear sky, since blue has a shorter wavelength and is ...
Since wavelength of blue color is approximately half the wavelength of red color, the scattering of blue light is about 2 4 times more than red light. Due to this blue color predominates and the sky appears blue.
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. The white light from the sun is a mixture of all colours of the ...
Blue light has the smallest wavelength. Thus it gets scattered the most. And the sky appears blue during the day. During sunrise and sunset, the sunlight travels a longer distance through the atmosphere, thus all the blue components of the light get scattered, and the sky appears reddish. Step 2: Explanation for the incorrect options:
This phenomenon is termed a scattering of light. The intensity of scattered light depends on the size of the particles and the wavelength of the light. Shorter wavelength and high-frequency scatter more due to the waviness of the line and its intersection with a particle. The wavier the line, the more the chance it intersects with a particle.
Blue light is scattered more than the other colours because it has the shortest wavelength. This is why the sky appears blue to an observer from the surface of the Earth. For an astronaut staying in the international space station orbiting the Earth, the colour of the sky will be black because the light reaching it does not scatter
The air is perfect scatterer agent for blue & violet color. That is the reason why we see sky blue. Or. When the sun's light reaches the Earth's atmosphere it is scattered, or deflected, by the tiny molecules of gas (mostly nitrogen and oxygen) in the air. Because these molecules are much smaller than the wavelength of visible light, the amount ...
Solution. To an astronaut, the sky looks dark and black instead of blue because there is no atmosphere containing air in the outer space to scatter sunlight. So, there is no scattered light to reach our eyes in outer space, therefore the sky looks dark and black there. Suggest Corrections. 550.
The clear sky appears blue because. (a) blue light gets absorbed in the atmosphere. (b) ultraviolet radiations are absorbed in the atmosphere. (c) violet and blue lights get scattered more than lights of all other. colours by the atmosphere. (d) light of all other colours is scattered more than the violet and. blue colour lights by the atmosphere.
