To explain the reddish appearance of the sun at sunrise or sunset and why it does not appear red at noon, we can follow these steps: ### Step 1: Understanding Rayleigh Scattering - **Explanation**: The phenomenon of scattering of light is described by Rayleigh's law of scattering. According to this law, the amount of scattering is inversely proportional to the fourth power of the wavelength of light. This means shorter wavelengths (like violet) scatter more than longer wavelengths (like red). ### Step 2: Wavelength Comparison - **Explanation**: The wavelength of red light is longer than that of violet light. Since violet light scatters more due to its shorter wavelength, it is scattered in all directions in the atmosphere, while red light, having a longer wavelength, scatters less. ...
