Explanation:
The correct statement among the given options is statement 3, "In the absence of atmosphere, there would be no scattering of light and the sky will look black."
Statement 1:
Clear sky appears blue due to the phenomenon of Rayleigh scattering. When sunlight enters the Earth's atmosphere, it interacts with the molecules and particles present in the atmosphere. The molecules in the atmosphere scatter the sunlight in all directions. The scattering of light occurs when the wavelength of light is similar in size to the particles or molecules in the atmosphere.
The blue part of the visible light spectrum has a shorter wavelength compared to the other colors. The molecules in the atmosphere, such as nitrogen and oxygen, have a size that is similar to the wavelength of blue light. As a result, blue light is scattered more than other colors in the spectrum. When we look at the sky, we see the scattered blue light, giving the sky a blue appearance.
Statement 2:
The statement that the red part of light shows more scattering than blue light in the atmosphere is incorrect. As explained in statement 1, blue light is scattered more than other colors due to its shorter wavelength. Red light, on the other hand, has a longer wavelength and is scattered less compared to blue light. This is the reason why the sky appears blue and not red.
Statement 3:
In the absence of an atmosphere, there would be no scattering of light. When there is no atmosphere to interact with sunlight, the light would travel in a straight path and not scatter in different directions. As a result, the sky would appear black, as there would be no scattered light reaching our eyes.
Overall, statement 3 is the only correct statement among the given options.
