Solution The correct option is C (adsbygoogle = window.adsbygoogle || []).push({}); Black If there is no atmosphere, there will be no scattering of sunlight at all. In that case, no scattered light will enter our eyes from the sky and the sky will look dark. Only the stars will appear as dots.Textbooks Question Papers Home What would be the colour of sky if earth had no atmosphere and why? Solution Yes. Earth's sky is blue because it's atmosphere scatters sunlight in random directions. If you are looking at a point in the sky that is blue, you are looking at light that originated from the direction of the sun that got bounced around a bunch of times in all different directions until it finally reached your eye. With no atmosphere, the background sky would be black because all the light from the sun and other sources would follow straight paths to your eye.Textbooks Question Papers Home In the absence of atmosphere, the sky appears, A. colored.B. blueC. indigoD. blackAnswer Verified Hint: We see various different colors due to the wavelength of each color. Each color has a specific wavelength. Each wavelength activates different cells in the retinas. These wavelengths are scattered as they travel a long distance through the atmosphere. We will try to find the relation between wavelength and scattering. Complete answer: So, the correct answer is “Option D”. Additional Information: Note: What would you see if there was no atmosphere?The Earth's sky would look like that. All unprotected plant and animal life on the Earth's surface would die. We can't survive long in a vacuum, which is what we'd have if the atmosphere suddenly vanished. It would be much like being "spaced' or shot out of an airlock, except the initial temperature would be higher.
What does the sky look like on a planet with no atmosphere?It would turn black. The sky appears blue because the light emitted from the sun gets scattered as it enters our atmosphere. The blue color that we see in the sky is due to this scattering of light.
What color was the sky before oxygen?Actually, the sky was orange until about 2.5 billion years ago, but if you jumped back in time to see it, you'd double over in a coughing fit. Way back then, the air was a toxic fog of vicious vapors: carbon monoxide, carbon dioxide, nitrogen, cyanide, and methane.
How would sun look if Earth had no atmosphere?Due to this reason, we usually see the sun to be yellow or red, or orange. However, if there is no atmosphere, there won't be any scattering of light, due to this all the wavelengths will reach our eyes at the same time. Thereby, we would see the sun in its actual color, that is, white.
