The correct Answer is:
To solve the question regarding the maximum scattering of sunlight by air molecules in the Earth's atmosphere, we will follow these steps: ### Step-by-Step Solution: 1. **Understanding Scattering**: - Scattering is the process by which small particles or molecules in the atmosphere deflect light in different directions. The amount of scattering depends on the wavelength of the light. 2. **Rayleigh Scattering**: - The phenomenon responsible for the scattering of light in the atmosphere is known as Rayleigh scattering. It states that shorter wavelengths of light (blue and violet) are scattered more than longer wavelengths (red and orange). 3. **Identifying Wavelengths**: - In the visible spectrum, blue light has a shorter wavelength compared to red light. Therefore, according to Rayleigh scattering, blue light will be scattered more effectively by air molecules. 4. **Observation of the Sky**: - On a clear, cloudless day, the sky appears blue because the blue light from the sun is scattered in all directions by the air molecules. 5. **Conclusion**: - Since blue light is scattered more than other colors in the white light spectrum of the sun, the answer to the question is that maximum scattering occurs for blue light. ### Final Answer: The maximum scattering by the air molecules present in the Earth's atmosphere in the white light of the Sun is for **blue light**. ---

Which was not present freely in the early atmosphere of the earth?

When the sun is either rising or setting and appears to be just in the horizon, it is in fact below the horizon. The explanation for this seeming paradox is that light from the sun bends slightly when entering the earth's atmosphere as shown in figure. Assume that the atmosphere has uniform density and hence uniform index of refraction n and extends to a height h above the earth's surface, at which point is abruptly stop. The angle delta above the Sun's true position is given by

Statemet-1: the electrical conductivity of earth's atmosphere increases with altitude. Statement -2: The high energy particles (i.e., gamma - rays and cosmic rays) coming from outer space while entering our earth's atmosphere cause ionization of the atoms of the gases present in the atmosphere and their energy decreases as they approach to earth.

Statement-1 : On viewing the clear blue portion of the sky through a Calcite Crystal, the intensity of transmitted light varies as the crystal is rotated. Statement-2 : The light coming from the sky is polarized due to scattering of sun light by particles in the atmoshphere. The scattering is largest for blue light.
